Long Throw Nozzle Grille with Integrated Round Duct Model WGA-V-RR
Description
Accessories
In modern architecture, sheet metal and spiral ducts of air-conditioning systems are often incorporated in the design of the
room. Emphasis is often placed deliberately on parts of the
supply system. In this visible installation of the ventilation
ducts, it is a good idea to integrate the air diffusers into the
ducts.
In order to be able to offer planners a technically advanced air
diffuser, which can also be readily integrated into modern architectural concepts, we have developed our round duct long throw
nozzle grille.
The round duct long range grille type WGA-V-RR is suitable for
use in supply air installations. The diffuser type WGA-V-RR consists of a round duct with integrated, linear long throw nozzles, which can also be adjusted by hand on-site. The pivot
angle is 45°. The round duct long throw grilles must therefore
be installed in accordance with the air direction required, so that
the nozzles blow the supply air either horizontally to the left/
right, or vertically into the room.
A hit-and-miss damper, which ensures that the supply air is discharged uniformly across the whole diffuser area, can be integrated into the diffuser. Therefore, the long throw nozzle with
integrated round duct type WGA-V-RR can be installed at any
point along this duct system.
Accessories, such as dummy pipes, end covers and connecting
sleeves complete the range for this diffuser. (See documents:
Accessories for round duct systems).

Attention!
We would like to point out that for cleaning stainless steel models,
only suitable cleaning materials may be used!
In order to avoid corrosion-caused damage, we recommend
subjecting the components in the natural aluminium design onsite to an after-treatment by anodisation or painting.
