Facade ventilation grille with back-draft valve, Ø150/160 mm, 19×19 cm, grey

Finishes the exterior wall opening of an exhaust or supply ventilation duct in residential, commercial and industrial buildings. The grille covers the facade opening and keeps rain, wind and insects out of the ventilation duct.

Made of UV- and weather-resistant ASA plastic that withstands sun, frost and temperature swings without fading or warping, so it keeps its colour and shape outdoors for years. It is built from two parts (flanged frame + hinged cover), which makes cleaning and maintenance easy. The 19×19 cm flange connects directly to a round duct of matching diameter (fits both 150 mm and 160 mm ducts).

The built-in gravity (self-acting) back-draft valve opens under airflow when the fan is running and closes on its own when the fan stops, preventing cold air, odours and draughts from coming back into the room. It can be fitted with screws or adhesive, and is also available in other colours to match the facade.
