Vents SD 100 nozzle diffuser is used in ventilation and air conditioning systems to supply supply air over a considerable distance due to the high speed of the supply jet. Maximum air flow 141 m3/h, maximum air speed 20 m/s. Such ventilation supply grilles are used for ventilation of large volume commercial or industrial premises with high ceilings.
Design
Made of anodized aluminum, rebates with holes are provided for fastening to air ducts. The supply air stream, moving in the ventilated area, reduces its speed, changes temperature and deviates upward if it is warm air or downward if it is cold air.
