Ceiling swirl diffuser DQJSLC Description The ceiling swirl diffuser type DQJSLC-... developed for use in comfort rooms is suitable for mounting heights of up to 4 m. It is provided with an external diffuser ring, which deflects part of the supply air horizontally. The horizontal throw forms an air cushion along the ceiling. This air cushion keeps any dust particles contained in the room air away from the ceiling. Consequently, the ceiling is less contaminated. The laminar flow exiting through the perforated plate is guided by the support jet created by the blades. The blades can be adjusted...
