Nozzle Jet Diffuser Model DSA DSA-F0-... Description Application The nozzle jet diffuser type DSA was developed especially to keep large windows free from condensation. Its high penetration depths, despite small air volumes, and its favourable acoustic behaviour allow it to be used for a wide range of different applications. The jet nozzle diffuser type DSA is suitable for installation in ceilings and floors. To achieve a flat surface, a cover plate, which conceals the nozzles, can be installed. The models with adjustable nozzles allow virtually unlimited settings, as the nozzles can be...
