Aluminium weather protection grille Ø 315 mm

Slide-in backflow flap / internal non-return flap Nominal width 100 mm to 200 mm Opens smoothly, low pressure loss Closes securely, no noise, no rattling The damper is inserted into the ventilation duct For vertical and horizontal installation Housing: Galvanised steel Damper blade: Aluminium Shaft and spring: Stainless steel The non-return damper is used in round ventilation ducts to prevent air backflow. The casing is made of galvanised sheet steel. The damper blades are made of aluminium and the shaft and spring are made of stainless steel. The internal rubber seal reduces noise. The outer foam strip provides a good seal and secures the non-return flap in the pipe. The non-return damper is designed for operation at ambient temperatures up to 60°C, for the transport of clean air, free of coarse dust, grease, chemical vapours and other impurities.
