DescriptionApplicationThe nozzle jet diffuser type DSA was developed especially tokeep large windows free from condensation. Its high penetra-tion depths, despite small air volumes, and its favourableacoustic behaviour allow it to be used for a wide range of dif-ferent applications. The jet nozzle diffuser type DSA is suitablefor installation in ceilings and floors. To achieve a flat surface, acover plate, which conceals the nozzles, can be installed.The models with adjustable nozzles allow virtually unlimited set-tings, as the nozzles can be adjusted individually to the desiredthrow direction. The nozzle jet diffusers are available in one- ortwo-row versions.

Attention:Please note the adjustable nozzles may only be cleaned by wip-ing the nozzle with little pressure.
The nozzle jet diffuser DSA can be used up to a room tempera-ture of +50 °C.
