❏
Read starting check points under OPERATION. Run
equipment briefly to check for installation errors and
make corrections. Follow with a trial run under normal
operating conditions.
❏
In event of trouble during installation or operation, do
not attempt repairs of ROOTS furnished equipment.
Notify ROOTS, giving all nameplate information plus an
outline of operating conditions and a description of the
trouble. Unauthorized attempts at equipment repair may
void ROOTS warranty.
❏
Units out of warranty may be repaired or adjusted by the
owner. Good inspection and maintenance practices
should reduce the need for repairs.
❏
Check shipment for damage. If found, file claim with
carrier and notify ROOTS.
❏
Unpack shipment carefully, and check contents against
Packing List. Notify ROOTS if a shortage appears.
❏
Store in a clean, dry location until ready for installation.
Lift by methods discussed under INSTALLATION to
avoid straining or distorting the equipment. Keep covers
on all openings. Protect against weather and corrosion if
outdoor storage is necessary.
❏
Read OPERATING LIMITATIONS and INSTALLATION sections in this manual and plan the complete installation.
❏
Provide for adequate safeguards against accidents to
persons working on or near the equipment during both
installation and operation. See SAFETY PRECAUTIONS.
NOTE: Information in this manual is correct as of the date of
publication. ROOTS reserves the right to make design or

Safety Precautions
It is important that all personnel observe safety precautions
to minimize the chances of injury. Among many considerations, the following should be particularly noted:
•
•
Blower casing and associated piping or accessories may
become hot enough to cause major skin burns on contact.
Internal and external rotating parts of the blower and
driving equipment can produce serious physical injuries.
Do not reach into any opening in the blower while it is
operating, or while subject to accidental starting. Protect
external moving parts with adequate guards.
•
Disconnect power before doing any work, and avoid
bypassing or rendering inoperative any safety or protective devices.
•
If blower is operated with piping disconnected, place a
strong coarse screen over the inlet and avoid standing in
the discharge air stream. CAUTION: Never cover the
blower inlet with your hand or other part of body.
•
Stay clear of the blast from pressure relief valves and the
suction area of vacuum relief valves.
•
Use proper care and good procedures in handling, lifting,
installing, operating and maintaining the equipment.
•
Casing pressure must not exceed 25 PSI (1725 mbar)
gauge. Do not pressurize vented cavities from an external
source, nor restrict the vents without first consulting
ROOTS.
•
Do not use air blowers on explosive or hazardous gases.
•
Other potential hazards to safety may also be associated
with operation of this equipment. All personnel working
in or passing through the area should be trained to exercise adequate general safety precautions.
•
Measured temperature rise must not exceed listed values when the inlet is at ambient temperature. Ambient
is considered as the general temperature of the space
around the unit. This is not outdoor temperature unless
the unit is installed outdoors.
•
If inlet temperature is higher than ambient, the listed
allowable temperature rise values must be reduced by
2/3 of the difference between the actual measured inlet
temperature and the ambient temperature.
•
The average of the inlet and discharge temperature must
not exceed 250°F. (121°C).
•
The ambient temperature of the space the blower/motor
is installed in should not be highter than 120°F (48.8°C).
Operating Limitations
A ROOTS blower or exhauster must be operated within certain approved limiting conditions to enable continued satisfactory performance. Warranty is contingent on such operation.
Maximum limits for pressure, temperature and speed are
specified in TABLE 1 for various models & sizes of blowers &
exhausters. These limits apply to all units of normal construction, when operated under standard atmospheric conditions. Be sure to arrange connections or taps for instruments, thermometers and pressure or vacuum gauges at or
near the inlet and discharge connections of the unit. These,
along with a tachometer, will enable periodic checks of operating conditions.
PRESSURE – The pressure rise, between inlet and discharge,
must not exceed the figure listed for the specific unit frame
size concerned. Also, in any system where the unit inlet is at
a positive pressure above atmosphere a maximum case rating of 25 PSI gauge (1725 mbar) should not be exceeded
without first consulting the ROOTS. Never should the maximum allowable differential pressure be exceeded.
On vacuum service, with the discharge to atmospheric pressure, the inlet suction or vacuum must not be greater than
values listed for the specific frame size.
TEMPERATURE – Blower & exhauster frame sizes are
approved only for installations where the following temperature limitations can be maintained in service:
SPEED – These blowers & exhausters may be operated at
speeds up to the maximum listed for the various frame sizes.
They may be direct coupled to suitable constant speed drivers if pressure/temperature conditions are also within limits.
At low speeds, excessive temperature rise may be a limiting
factor.
Special Note: The listed maximum allowable temperature
rise for any particular blower & exhauster may occur well
before its maximum pressure or vacuum rating is reached.
This may occur at high altitude, low vacuum or at very low
speed. The units’ operating limit is always determined by the
maximum rating reached first. It can be any one of the three:
Pressure, Temperature or Speed.
For your nearest ROOTS office contact information, please consult the last page of this document.

Installation
ROOTS blowers & exhausters are treated after factory
assembly to protect against normal atmospheric corrosion.
The maximum period of internal protection is considered to
be one year under average conditions, if shipping plugs &
seals are not removed. Protection against chemical or salt
water atmosphere is not provided. Avoid opening the unit
until ready to start installation, as corrosion protection will
be quickly lost due to evaporation.
If there is to be an extended period between installation and
start up, the following steps should be taken to ensure corrosion protection.
❏
Coat internals of cylinder, gearbox and drive end bearing
reservoir with Nox-Rust VCI-10 or equivalent. Repeat
once a year or as conditions may require. Nox-Rust
VCI-10 is petroleum soluble and does not have to be
removed before lubricating. It may be obtained from
Daubert Chemical Co., 2000 Spring Rd., Oak Brook, Ill.
60521.
❏
Paint shaft extension, inlet and discharge flanges, and all
other exposed surfaces with Nox-Rust X-110 or equivalent.
❏
Seal inlet, discharge, and vent openings. It is not recommended that the unit be set in place, piped to the
system, and allowed to remain idle for extended periods.
If any part is left open to the atmosphere, the Nox-Rust
VCI-10 vapor will escape and lose its effectiveness.
❏
Protect units from excessive vibration during storage.
❏
Rotate shaft three or four revolutions every two weeks.
❏
Prior to start up, remove flange covers on both inlet and
discharge and inspect internals to insure absence of
rust. Check all internal clearances. Also, at this time,
remove gearbox and drive end bearing cover and inspect
gear teeth and bearings for rust.
Because of the completely enclosed unit design, location of
the installation is generally not a critical matter. A clean, dry
and protected indoor location is preferred. However, an outdoor location will normally give satisfactory service.
Important requirements are that the correct grade of lubricating oil be provided for expected operating temperatures, and
that the unit be located so that routine checking and servicing can be performed conveniently. Proper care in locating
driver and accessory equipment must also be considered.
Supervision of the installation by a ROOTS Service Engineer
is not usually required for these units. Workmen with experience in installing light to medium weight machinery should
be able to produce satisfactory results. Handling of the
equipment needs to be accomplished with care, and in compliance with safe practices. Unit mounting must be solid,
without strain or twist, and air piping must be clean, accurately aligned and properly connected.
Bare-shaft Units: Two methods are used to handle a unit
without base. One is to use lifting lugs bolted into the top of
the unit headplates. Test them first for tightness and frac-
40
tures by tapping with a hammer. In lifting, keep the direction
of cable pull on these bolts as nearly vertical as possible. If
lifting lugs are not available, lifting slings may be passed
under the cylinder adjacent to the headplates. Either method
prevents strain on the extended drive shaft.
Packaged Units: When the unit is furnished mounted on a
baseplate, with or without a driver, use of lifting slings passing under the base flanges is required. Arrange these slings
so that no strains are placed on the unit casing or mounting
feet, or on any mounted accessory equipment. DO NOT use
the lifting lugs in the top of the unit headplates.
Before starting the installation, remove plugs, covers or seals
from unit inlet and discharge connections and inspect the
interior completely for foreign material. If cleaning is
required, finish by washing the cylinder, headplates and
impeller thoroughly with a petroleum solvent. Turn the drive
shaft by hand to make sure that the impellers turn freely at
all points. Anti-rust compound on the connection flanges
and drive shaft extension may also be removed at this time
with the same solvent. Cover the flanges until ready to connect piping.
Mounting
Care will pay dividends when arranging the unit mounting.
This is especially true when the unit is a “bare-shaft” unit
furnished without a baseplate. The convenient procedure
may be to mount such a unit directly on a floor or small concrete pad, but this generally produces the least satisfactory
results. It definitely causes the most problems in leveling
and alignment and may result in a “Soft Foot” condition.
Correct soft foot before operation to avoid unnecessary loading on the casing and bearings. Direct use of building structural framing members is not recommended.
For blowers without a base, it is recommended that a well
anchored and carefully leveled steel or cast iron mounting
plate be provided. The plate should be at least 1 inch (25
mm) thick, with its top surface machined flat, and large
enough to provide leveling areas at one side and one end
after the unit is mounted. It should have properly sized
studs or tapped holes located to match the unit foot drilling.
Proper use of a high quality machinist’s level is necessary for
adequate installation.
With the mounting plate in place and leveled, set the unit on
it without bolting and check for rocking. If it is not solid,
determine the total thickness of shims required under one
foot to stop rocking. Place half of this under each of the
diagonally-opposite short feet, and tighten the mounting
studs or screws. Rotate the drive shaft to make sure the
impellers turn freely. If the unit is to be direct coupled to a
driving motor, consider the height of the motor shaft and the
necessity for it to be aligned very accurately with the unit
shaft. Best unit arrangement is directly bolted to the mounting plate while the driver is on shims of at least 1/8 inch
(3mm) thickness. This allows adjustment of motor position
in final shaft alignment by varying the shim thickness.
Aligning
When unit and driver are factory mounted on a common
baseplate, the assembly will have been properly aligned and
is to be treated as a unit for leveling purposes. Satisfactory
installation can be obtained by setting the baseplate on a concrete slab that is rigid and free of vibration, and leveling the
top of the base carefully in two directions so that it is free of
twist. The slab must be provided with suitable anchor bolts.
The use of grouting under and partly inside the leveled and
shimmed base is recommended.
It is possible for a base-mounted assembly to become twisted during shipment, thus disturbing the original alignment.
For this reason, make the following checks after the base has
been leveled and bolted down. Disconnect the drive and
rotate the unit shaft by hand. It should turn freely at all
points. Loosen the unit foot hold-down screws and determine whether all feet are evenly in contact with the base. If
not, insert shims as required and again check for free
impeller rotation. Finally, if unit is direct coupled to the driver, check shaft and coupling alignment carefully and make
any necessary corrections.
In planning the installation, and before setting the unit, consider how piping arrangements are dictated by the unit
design and assembly. Drive shaft rotation must be established accordingly and is indicated by an arrow near the
shaft.
Typical arrangement on vertical units has the drive shaft at
the top with counterclockwise rotation and discharge to the
left. Horizontal units are typically arranged with the drive
shaft at the left with counterclockwise rotation and discharge
down. See Figure 4 for other various unit arrangements and
possible conversions.
When a unit is DIRECT COUPLED to its driver, the driver RPM
must be selected or governed so as not to exceed the maximum speed rating of the unit. Refer to Table 1 for allowable
speeds of various unit sizes.
A flexible type coupling should always be used to connect the
driver and unit shafts.
When direct coupling a motor or engine to a blower you must
insure there is sufficient gap between the coupling halves and
the element to prevent thrust loading the blower bearings.
When a motor, engine or blower is operated the shafts may
expand axially. If the coupling is installed in such a manner
that there is not enough room for expansion the blower shaft
can be forced back into the blower and cause the impeller to
contact the gear end headplate resulting in damage to the
blower. The two shafts must be in as near perfect alignment
in all directions as possible, and the gap must be established
with the motor armature on its electrical center if end-play
exists. Coupling manufacturer’s recommendations for maximum misalignment, although acceptable for the coupling, are
normally too large to achieve smooth operation and maximum life of the blower.
The following requirements of a good installation are recommended. When selecting a coupling to be fitted to the blower
shaft ROOTS recommends a taper lock style coupling to
insure proper contact with the blower shaft. If the coupling
must have a straight bore the coupling halves must be fitted
to the two shafts with a line to line thru .001” interference fit.
Coupling halves must be warmed up per coupling manufacturer’s recommendations. Maximum deviation in offset alignment of the shafts should not exceed .005” (.13 mm) total
indicator reading, taken on the two coupling hubs. Maximum
deviation from parallel of the inside coupling faces should not
exceed .001” (.03 mm) when checked at six points around
the coupling.
When a unit is BELT DRIVEN, the proper selection of sheave
diameters will result in the required unit speed. When selecting a sheave to be fitted to the blower shaft ROOTS recommends a taper lock style sheave to insure proper contact with
the blower shaft. This flexibility can lead to operating temperature problems caused by unit speed being too low. Make
sure the drive speed selected is within the allowable range for
the specific unit size, as specified under Table 1.
Belt drive arrangements usually employ two or more V-belts
running in grooved sheaves. Installation of the driver is less
critical than for direct coupling, but its shaft must be level
and parallel with the unit shaft. The driver should be mounted on the inlet side of a vertical unit (horizontal piping) and
on the side nearest to the shaft on a horizontal unit. SEE
PAGE 6 - Acceptable Blower Drive Arrangement Options.
The driver must also be mounted on an adjustable base to
permit installing, adjusting and removing the V-belts. To
position the driver correctly, both sheaves need to be mounted on their shafts and the nominal shaft center distance
known for the belt lengths to be used.
CAUTION: Drive couplings and sheaves (pulleys) should have
an interference fit to the shaft of the blower (set screw types
of attachment generally do not provide reliable service.) It is
recommended that the drive coupling or sheave used have a
taper lock style bushing which is properly sized to provide the
correct interference fit required. Drive couplings, that require
heating to fit on the blower shaft, should be installed per coupling manufacturer recommendations. A drive coupling or
sheave should not be forced on to the shaft of the blower as
this could affect internal clearances resulting in damage to
the blower.
Engine drive applications often require special consideration
to drive coupling selection to avoid harmful torsional vibrations. These vibrations may lead to blower damage if not
dampened adequately. It is often necessary to install a flywheel and/or a torsionally soft elastic element coupling
based on the engine manufacturer recommendations.
The driver sheave should also be mounted as close to its
bearing as possible, and again should fit the shaft correctly.
Position the driver on its adjustable base so that 2/3 of the
total movement is available in the direction away from the
unit, and mount the assembly so that the face of the sheave
is accurately in line with the unit sheave. This position minimizes belt wear, and allows sufficient adjustment for both
installing and tightening the belts. After belts are installed,
adjust their tension in accordance with the manufacturer’s
instructions. However, only enough tension should be
applied to prevent slippage when the unit is operating under
load. Excessive tightening can lead to early bearing concerns
or shaft breakage.
Before operating the drive under power to check initial belt
tension, first remove covers from the unit connections. Make
sure the interior is still clean, then rotate the shaft by hand.
Place a coarse screen over the inlet connection to prevent
anything being drawn into the unit while it is operating, and
avoid standing in line with the discharge opening. Put oil in
the sumps per instructions under LUBRICATION.
Piping
Before connecting piping, remove any remaining anti-rust
compound from unit connections. Clean pipe should be no

smaller than unit connections. In addition, make sure it is
free of scale, cuttings, weld beads, or foreign material of any
kind. To further guard against damage to the unit, especially
when an inlet filter is not used, install a substantial screen of
16 mesh backed with hardware cloth at or near the inlet connections. Make provisions to clean this screen of collected
debris after a few hours of operation. It should be removed
when its usefulness has ended, as the wire will eventually
deteriorate and small pieces going into the unit may cause
serious damage.
Pipe flanges or male threads must meet the unit connections
accurately and squarely. DO NOT attempt to correct misalignment by springing or cramping the pipe. In most cases
this will distort the unit casing and cause impeller rubbing.
In severe cases it can prevent operation or result in a broken
drive shaft. For similar reasons, piping should be supported
near the unit to eliminate dead weight strains. Also, if pipe
expansion is likely to occur from temperature change, installation of flexible connectors or expansion joints is advisable.
Figure 3 represents an installation with all accessory items
that might be required under various operating conditions.
Inlet piping should be completely free of valves or other
restrictions. When a shut-off valve can not be avoided, make
sure a full size vacuum relief is installed nearest the unit inlet.
This will protect against unit overload caused by accidental
closing of the shut-off valve.
Need for an inlet silencer will depend on unit speed and pressure, as well as sound-level requirements in the general surroundings. An inlet filter is recommended, especially in dusty

or sandy locations. A discharge silencer is also normally
suggested, even though Whispair units operate at generally
lower noise levels than conventional rotary blowers. Specific
recommendations on silencing can be obtained from your
local ROOTS distributor.
Discharge piping requires a pressure relief valve, and should
include a manual unloading valve to permit starting the unit
under no-load conditions. Reliable pressure/vacuum gauges
and good thermometers at both inlet and discharge are recommended to allow making the important checks on unit
operating conditions. The back-pressure regulator shown in
Figure 3 is useful mainly when volume demands vary while
the unit operates at constant output. If demand is constant,
but somewhat lower than the unit output, excess may be
blown off through the manual unloading valve.
In multiple unit installations where two or more units operate
with a common header, use of check valves is mandatory.
These should be of a direct acting or free swinging type, with
one valve located in each line between the unit and header.
Properly installed, they will protect against damage from
reverse rotation caused by air and material back-flow through
an idle unit.
After piping is completed, and before applying power, rotate
the drive shaft by hand again. If it does not move with uniform freedom, look for uneven mounting, piping strain,
excessive belt tension or coupling misalignment.
DO NOT operate the unit at this time unless it has been lubricated per instructions.
Technical Supplement for URAI® Gas Blowers
Technical Supplement for 32, 33, 36, 42, 45, 47, 53, 56, 59,
65, 68, 615 Universal RAI-G blowers
ROOTS Universal RAI-G rotary positive gas blowers are a
design extension of the basic Universal RAI blower model.
URAI-G blower uses (4) mechanical seals in place of the
standard inboard lip seals to minimize gas leakage into the
atmosphere. The seal vent chambers are plugged. These
units are intended for gases which are compatible with cast
iron case material, steel shafts, 300/400 series stainless steel
and carbon seal components, viton o-rings and the oil/grease
lubricants. If there are any questions regarding application or
operation of this gas blower, please contact factory.
Precaution: URAI-G blowers: Care must be used when
opening the head plate seal vent chamber plugs (43) as
some gas will escape–if it is a pressure system, or the
atmospheric air will leak in-if the system is under vacuum.
There is a possibility of some gas leakage through the
mechanical seals. This leakage on the gear end will escape
through the gear box vent, and on the drive end, through the
grease release fittings. If the gas leakage is undesirable,
each seal chamber must be purged with an inert gas
through one purge gas hole (43) per seal . There are two
plugged purge gas holes(1/8 NPT) provided per seal. The
purge gas pressure must be maintained one psi above the
discharge gas pressure. Also, there exists a possibility of
gear end oil and drive end grease leakage into the gas
stream.
The lubricants selected must be compatible with the gas.
URAI GAS Blower Oil and Grease Specifications
The specified oil should be ROOTS synthetic P/N 813-106- of
the proper viscosity.
When servicing drive end bearings of a Gas blower, use the
specified NLGI #2 premium grade aluminum complex*
grease, ROOTS P/N T20019001, with 300°F (149°C) service
temperature and moisture resistance and good mechanical
stability.
*ROOTS Synthetic Oil & Grease is superior in performance to
petroleum based products. It has high oxidation stability, excellent corrosion
protection, extremely high film strength and low coefficient of friction. Typical
oil change intervals are increased 2-3 times over petroleum based lubricants.
Also, ROOTS Synthetic Oil is 100% compatible with petroleum based oils.
Simply drain the oil in the blower and refill the reservoirs with ROOTS Synthetic
Oil to maintain optimum performance of your ROOTS blower.

Lubrication
For Units with a Grease Lubricated Drive End
and is drained downward.
A simple but very effective lubrication system is employed on
the drive shaft end bearings. Hydraulic pressure relief fittings
are provided to vent any excess grease, preventing pressure
build-up on the seals. A restriction plug and metering orifice
prevent loss of lubricant from initial surges in lubricant pressure but permit venting excess lubricant under steadily rising
pressures.
Oil sumps on each end of the blower are filled by removing
top vent plugs, Item (25), and filling until oil reaches the middle of the oil level sight gauge, Item (45 or 53), or the overflow plug (see pages 14 and 15).
When servicing drive end bearings of Non Gas blower, use
the specified NLGI #2 premium grade microgel grease with
250°F (121°C) service temperature and moisture resistance
and good mechanical stability. ROOTS specifies Shell Darina
EP NLGI Grade 2. Product Code 71522.
URAI GAS Blower Oil and Grease Specifications
The specified oil should be ROOTS synthetic P/N 813-106- of
the proper viscosity.
When servicing drive end bearings of a Gas blower, use the
specified NLGI #2 premium grade aluminum complex*
grease, ROOTS P/N T20019001, with 300°F (149°C) service
temperature and moisture resistance and good mechanical
stability.
NOTE: Lithium based greases are not compatible with the
ROOTS Synthetic grease used when assembling a Gas blower or the non-soap base grease used when assembling a
standard URAI blower. Lithium based grease is not
approved for any ROOTS blowers.
Using a pressure gun, slowly force new lubricant into each
drive end bearing housing until traces of clean grease comes
out of the relief fitting. The use of an electric or pneumatic
grease gun could force the grease in too rapidly and thus
invert the seals and should not be used.
After a long shutdown, it is recommended that the grease fittings be removed, the old grease flushed out with kerosene
or #10 lubricating oil, drained thoroughly, and bearings
refilled with new grease. Be sure grease relief fittings are
reinstalled. Grease should be added using a hand operated
grease gun to the drive end bearings at varying time intervals
depending on duty cycle and RPM. Table 4 has been prepared as a general greasing schedule guide based on average
operating conditions. More frequent intervals may be necessary depending on the grease operating temperature and
unusual circumstances.
For Units with Splash Lubrication on Both Ends
Bearings and oil seals are lubricated by the action of the timing gears or oil slingers which dip into the main oil sumps
causing oil to splash directly on gears and into bearings and
seals. A drain port is provided below each bearing to prevent
an excessive amount of oil in the bearings. Seals located
inboard of the bearings in each headplate effectively retain oil
within the sumps. Any small leakage that may occur should
the seals wear passes into a cavity in each vented headplate
44
Initial filling of the sumps should be accomplished with the
blower not operating, in order to obtain the correct oil level.
Approximate oil quantities required for blowers of the various
models and configurations are listed in Table 3. Use a good
grade of industrial type non-detergent, rust inhibiting, antifoaming oil and of correct viscosity per Table 2. *ROOTS synthetic oil (ROOTS P/N 813-106-) is highly recommended.
ROOTS does not recommend automotive type lubricants, as
they are not formulated with the properties mentioned above.
The oil level should not fall below the middle of the site gauge
or overflow plug on URAI (ref. pages 14 & 15) when the
blower is idle. It may rise or fall on the gauge during operation, to an extent depending somewhat on oil temperature
and blower speed.
Proper lubrication is usually the most important single consideration in obtaining maximum service life and satisfactory
operation from the unit. Unless operating conditions are quite
severe, a weekly check of oil level and necessary addition of
lubricant should be sufficient. During the first week of operation, check the oil levels in the oil sumps about once a day,
and watch for leaks. Replenish as necessary. Thereafter, an
occasional check should be sufficient. It is recommended that
the oil be changed after initial 100 hours of operation.
Frequent oil changing is not necessary unless the blower is
operated in a very dusty location.
Normal life expectancy of petroleum based oils is about 2000
hours with an oil temperature of about 180°F (82°C). As the
oil temperature increases by increments of 15-18°F (8°C 10°C), the life is reduced by half. Example: Oil temperatures
of 210-216°F (99°C - 102°C) will produce life expectancy of
1/4 or 500 hours. Therefore, it is considered normal to have
oil change periods of 500 hours with petroleum based oils.
Normal life expectancy of ROOTS™ Synthetic Oil is about 4000
to 8000 hours with an oil temperature of about 180°F (82°C).
As the oil temperature increases by increments of 15-18°F
(8°C - 10°C), the life is reduced by half. Example: Oil temperatures of 210-216°F (99°C - 102°C) will produce life
expectancy of 1/4 or 1000 to 2000 hours.
NOTE: To estimate oil temperature, multiply the discharge
temperature of the blower by 0.80. Example: if the discharge
air temperature of the blower is 200° F, it is estimated that
the oil temperature is 160° F.
*ROOTS™ Synthetic Oil & Grease is superior in performance to petroleum based products. It has high oxidation stability, excellent corrosion protection, extremely high film
strength and low coefficient of friction. Typical oil change intervals are increased 2-3
times over petroleum based lubricants. Also, ROOTS™ Synthetic Oil is 100% compatible
with petroleum based oils. Simply drain the oil in the blower and refill the reservoirs
with ROOTS™ Synthetic Oil to maintain optimum performance of your ROOTS™ blower.
Operation
Before operating a blower under power for the first time,
recheck the unit and the installation thoroughly to reduce the
likelihood of avoidable troubles. Use the following procedure
check list as a guide, but consider any other special conditions in the installation.
❏
Be certain that no bolts, tools, rags, or debris have been
left in the blower air chamber or piping.
❏
If an outdoor intake without filter is used, be sure the
opening is located so it cannot pick up dirt and is protected by a strong screen or grille. Use of the temporary
protective screen as described under INSTALLATION is
strongly recommended.
❏
Recheck blower leveling, drive alignment and tightness
of all mounting bolts if installation is not recent. If belt
drive is used, adjust belt tension correctly.
❏
Turn drive shaft by hand to make sure impellers still
rotate without bumping or rubbing at any point.
❏
Ensure oil levels in the main oil sumps are correct.
❏
Check lubrication of driver. If it is an electric motor, be
sure that power is available and that electrical overload
devices are installed and workable.
❏
Open the manual unloading valve in the discharge air
line. If a valve is in the inlet piping, be sure it is open.
❏
Bump blower a few revolutions with driver to check that
direction of rotation agrees with arrow near blower
shaft, and that both coast freely to a stop.
After the preceding points are cleared, blower is ready for
trial operation under “no-load” conditions. The following
procedure is suggested to cover this initial operation test
period.
a.
Start blower, let it accelerate to full speed, then shut off.
Listen for knocking sounds, both with power on and as
speed slows down.
b.
After blower comes to a complete stop, repeat above,
but let blower run 2 or 3 minutes. Check for noises,
such as knocking sounds.
c.
After blower comes to a complete stop, operate blower
for about 10 minutes unloaded. Check oil levels.
Observe cylinder and headplate surfaces for development of hot spots such as burned paint, indicating
impeller rubs. Be aware of any noticeable increase in
vibration.
Assuming that all trials have been satisfactory, or that necessary corrections have been made, the blower should now
have a final check run of at least one hour under normal
operating conditions. After blower is restarted, gradually
close the discharge unloading valve to apply working pressure. At this point it is recommended that a pressure gauge
or manometer be connected into the discharge line if not
already provided, and that thermometers be in both inlet and
discharge lines. Readings from these instruments will show
whether pressure or temperature ratings of the blower are
being exceeded.
During the final run, check operating conditions frequently
and observe the oil levels at reasonable intervals. If excessive
noise or local heating develops, shut down immediately and
determine the cause. If either pressure rise or temperature
rise across the blower exceeds the limit specified in this
manual, shut down and investigate conditions in the piping
system. Refer to the TROUBLESHOOTING CHECKLIST for
suggestions on various problems that may appear.
The blower should now be ready for continuous duty operation at full load. During the first few days make periodic
checks to determine whether all conditions remain steady, or
at least acceptable. This may be particularly important if the
blower is supplying air to a process system where conditions
can vary. At the first opportunity, stop the blower and clean
the temporary inlet protective screen. If no appreciable
amount of debris has collected, the screen may be removed.
See comments under INSTALLATION. At this same time, verify leveling, coupling alignment or belt tension, and mounting
bolt tightness.
Should operating experience prove that blower capacity is a
little too high for the actual air requirements, a small excess
may be blown off continuously through the manual unloading or vent valve. Never rely on the pressure relief valve as
an automatic vent. Such use may cause the discharge pressure to become excessive, and can also result in failure of
the valve itself. If blower capacity appears to be too low, refer
to the TROUBLESHOOTING CHECKLIST.
Vibration Assessment Criteria
With measurements taken at the bearing locations on the
housings, see chart below for an appropriate assessment
guide for rotary lobe blowers rigidly mounted on stiff foundations.
In general, blower vibration levels should be monitored on a
regular basis and the vibration trend observed for progressive or sudden change in level. If such a change occurs, the
cause should be determined through spectral analysis.
As shown on the chart below, the level of all pass vibration
will determine the need to measure discrete frequency vibration levels and the action required.

Inspection & Maintenance: Universal RAI® series blowers
A good program of consistent inspection and maintenance is
the most reliable method of minimizing repairs to a blower. A
simple record of services and dates will help keep this work
on a regular schedule. Basic service needs are:
any reason. Some oil seal leakage may occur since an oil film
under the lip is required for proper operation. Periodically
leaked oil should be wiped off from surfaces. Minor seal
leakage should not be considered as indicating seal replacement.
•
Lubrication
•
Checking for hot spots
•
Checking for increases or changes in vibration and noise
•
Recording of operating pressures and temperatures
Timing gear wear, when correct lubrication is maintained,
should be negligible. Gear teeth are cut to provide the correct
amount of backlash, and gears correctly mounted on the
shafts will accommodate a normal amount of tooth wear
without permitting contact between lobes of the two
impellers. However, too high an oil level will cause churning
and excessive heating. This is indicated by unusually high
temperature at the bottom of the gear housing. Consequent
heating of the gears will result in loss of tooth-clearance ,
backlash and rapid wear of the gear teeth usually will develop. Continuation of this tooth wear will eventually produce
impeller contacts (knocking), and from this point serious
damage will be unavoidable if blower operation is continued.
A similar situation can be produced suddenly by gear tooth
fracture, which is usually brought on by sustained overloading or momentary shock loads.
Above all, a blower must be operated within its specified rating limits, to obtain satisfactory service life.
A newly installed blower should be checked often during the
first month of full-time operation. Attention there after may
be less frequent assuming satisfactory performance.
Lubrication is normally the most important consideration and
weekly checks of lubricant levels in the gearbox and bearing
reservoirs should be customary. Complete oil change schedules are discussed under LUBRICATION.
Driver lubrication practices should be in accordance with the
manufacturer’s instructions. If direct connected to the blower
through a lubricated type coupling, the coupling should be
checked and greased each time blower oil is changed. This
will help reduce wear and prevent unnecessary vibration. In a
belted drive system, check belt tension periodically and
inspect for frayed or cracked belts.
In a new, and properly installed, unit there is no contact
between the two impellers, or between the impellers and
cylinder or headplates. Wear is confined to the bearings
(which support and locate the shafts) the oil seals, and the
timing gears. All are lubricated and wear should be minimal
if clean oil of the correct grade is always used. Seals are subject to deterioration as well as wear, and may require replacement at varying periods.
Shaft bearings are designed for optimum life under average
conditions with proper lubrication and are critical to the service life of the blower. Gradual bearing wear may allow a shaft
position to change slightly, until rubbing develops between
impeller and casing. This will cause spot heating, which can
be detected by observing these surfaces. Sudden bearing
failure is usually more serious. Since the shaft and impeller
are no longer supported and properly located, extensive general damage to the blower casing and gears is likely to occur.
Problems may also develop from causes other than internal
parts failure. Operating clearances within a blower are only a
few thousandths of an inch. This makes it possible for
impeller interference or casing rubs to result from shifts in
the blower mounting, or from changes in piping support. If
this type of trouble is experienced, and the blower is found
to be clean, try removing mounting strains. Loosen blower
mounting bolts and reset the leveling and drive alignment.
Then tighten mounting again, and make sure that all piping
meets blower connections accurately and squarely Foreign
materials in the blower will also cause trouble, which can
only be cured by disconnecting the piping and thoroughly
cleaning the blower interior.
A wide range of causes & solutions for operating troubles
are covered in the TROUBLE SHOOTING CHECKLIST. The
remedies suggested should be performed by qualified
mechanics with a good background. Major repairs generally
are to be considered beyond the scope of maintenance, and
should be referred to an authorized ROOTS distributor.
Warranty failures should not be repaired at all, unless specific approval has been obtained through ROOTS before starting work. Unauthorized disassembly within the warranty period may void the warranty.
Oil seals should be considered expendable items, to be
replaced whenever drainage from the headplate vent cavity
becomes excessive or when the blower is disassembled for
