smoke extract fan

Systemair nozzle diffuser for duct mounting. The nozzles are adjusted individually (360°).

Sinus-DC/DR is a nozzle diffuser for duct mounting. Sinus-DC (for circular duct) and DR (for rectangular duct) consists of a frontplate with several nozzles and a check rail. The design of the nozzles enables the diffuser to achieve very high induction of room air. The Sinus-DC/DR can be used for both cooled and heated air. Max. temperature difference: dT 10 K. The nozzles can be individually set at any angle within 360°. This means that an unlimited number of distribution patterns can be set without affecting noise levels, air volume or pressure drop. The nozzles’ rounded edges prevent dust from settling and facilitate easy cleaning.

Sinus-DC/DR nozzle diffuser consists of a supply-air element (the front plate) and a check rail manufactured from galvanized sheet steel. The entire unit has a white powdercoated finish (RAL 9010-80). Around the edges of the front plate there is a seal tested for air-tightness made from polyten. The nozzles are made from recyclable ABS with a diameter of 57 mm, and are finished in standard white which matches RAL 9010-80.
