Why should FFU’s be used in cleanrooms?
Benefits which count …
... Redundancy
With hundreds, or thousands of individual FFU’s in a facility,
the loss of one or more units does not jeopardise the integrity of the room.
Nicotra Gebhardt
has developed control
software to monitor different
ventilating systems,
room configurations
and airflows.
Monitoring
... Flexibility
As the needs or uses change in a facility, the units can be
exchanged with lay-in lights or blank panels. For facilities
with lower classification, upgrades can be obtained by
simply adding additional FFU’s. When a computer controlled
management system is installed, units or clusters of units
can be remote controlled to operational needs.
... Cost effective
Use motors with the lowest power consumption available.
With complete controllability of each and every FFU (via
control and monitoring software) use just as much of power
as necessary for your process.
... Negative plenum
The negative plenum design draws recirculation air from
the plenum itself. If there are any leaks, they migrate to the
negative plenum and NOT the cleanroom.

... Salvageability
FFU’s are fully salvageable as stand alone units.

have brought forth over 50 years
of experience in leading-edge
fan design and highly efficient

Casing
Motors
Since the very beginning of
the Nicotra Gebhardt company the external rotor motor has
been an essential element for
driving fans.
Nicotra Gebhardt has a manu­
facturing facility for production of
external rotor motors – the conventional asynchronous version
and the electronically controlled
brushless DC design. An expert
team with special laboratories
and test rigs is pushing this development to new frontiers.
Filter Fan Units ar key
elements in clean room ventilation systems.
Nicotra Gebhardt supplies the
elements for Filter Fan Units (FFU)
as well as the units themselves.
Starting from standard FFU design, our team of experts implements the specification for your
special project.

What are the
exact dimensions required
for your ideal
FFU design?
Fans, motors and control units
may be of Nicotra Gebhardt
standard design or they may be
specially adapted to the actual
require­ments of a project.
Filter Fan Units (FFU) made by
Nicotra Gebhardt with their
perfectly matched components
are designed for various kinds of
industrial areas requiring clean

Casings
A system of standard sizes
makes it possible – by combining them in different ways
– to fill in every special shape
of a building and, in this way, to
create a filter fan ceiling, actively
covered by the most effective
filter fan units.

What flowrate/
air velocity do
you need?
What are your
noise criteria?
Nicotra Gebhardt offers software and hardware especially
developed to match the high
demands for a perfect clean
room system.
Any required flow of air can be
achieved by adjusting the fan
size or its rotating speed.
Uneven air flow distribution can
be caused by a poorly designed
ventilation system or by the uneven flow of air through the filter.

The demands of air flow uniformity
are magnified with the increased
requirements of higher room
cleanliness classifi­cations and
more end users are specifying
reduced variation of velocity
profiles.
Low noise
High efficiency includes low
noise levels.
Special sound measuring facilities make it possible to detect
every peak in frequency bands
and to improve a spectrum by
designing new noise patterns.

What about the
power supply?
Asynchronous motor
This type of motor is available as
an AC motor, wound in such a
way that speed control by simple
voltage variation is possible.
The motor is a standard and has
been on the market for about
50 years.
External rotor motors integrate
exceptionally well into a centrifugal fan impeller.
They don’t take up extra space
because they are entirely built in
the impeller without creating major disturbances to the air stream
through the impeller.
This design feature places the
motor directly in the air stream
and the cooling for the motor
cannot be better.

This allows the motor to operate
more efficiently and therefore
the motor size can be slightly
smaller than that of a standard
IEC motor.

What about the
electronics?

(Brushless DC motor)
The most advanced development is the EC motor which
exploits the basic external rotor
principle of a brushless DC
motor.

A drive unit consisting of an
electronically commutated motor
differs from the former DC motors as there are no collector or
carbon brushes.
These wearing components
have been replaced in an electronic commutated motor with
maintenance-free electronics
(control unit).
EC Motors
The EC motor has three winding
circuits, which are controlled by
the electronic commutation unit
with a changing current impulse.
To create a continuous rotating movement of the rotor, the
electric current must now be
switched relative to the position of the rotating permanent
magnet rotor field.
The electric current results in a
magnetic field which interacts
with the field of the permanent
magnets of the rotor. This generates a torque for the motor.
The position of the permanent
magnet is detected by hall effect
sensors and as a result of this
signal the control electronics
carry out the commutation.
This is how it works:

Monitoring
and
Controlling
The keypoint of the clean room
is the FFU, which can be selected in different performance /
efficiency / configuration and
used in different places in the
process or ventilating system.
Network Topology:
The Nicotra Gebhardt FFU Monitoring and Control System consists of a FFU control network
connected to a computerised
FFU Control centre. This FFU
System is especially made for
the high demands of clean room
applications.
The FFU Control centre allows
control of a large quantity of
FFUs in a very flexible and future
oriented way.
At the heart of the system is a
control centre (server) which
contains network management,
process control and web server
as main parts.

Topology Overview
This Figure shows the complete
FFU LAN-BUS control network
topology as recommended by
Nicotra Gebhardt.
The field bus section uses LANBUS technology in ring topology
for the Ethernet part and line
topology for the RS485 part.
The LAN-BUS is structured
with gateways with a redundant
Ethernet backbone and several
FFU lines.
Additional I/O modules for
connection to the server are also
available.
The FFU Server can be provided
with a redundancy server in hotstandby configuration.
