Supply nozzles are designed for the

supply of air to rooms with large

throw distance requirements and low

noise level. They are made of anodi-

zed aluminom or can be painted inany RAL colour. Fixed nozzles are in

range 50-200mm of outer diameter.

Application

Adjustable supply nozzles are designed

for the supply of air to rooms with large

throw distance requirements. With the

adjustable models, air jet direction can

be set, manually or with a motor drive,

within a +-30 degree range. They are

made of anodized aluminom or can be

painted in any RAL colour. Adjustable

nozzles are in range 100-400mm of in-

ner diameter.
