150mm stainless steel ventilation grille – Non-return valve with movable louvers – Weatherproof – Dimensions 184x184mm

The hood's outer grille acts as an external ventilation grille, covering the ventilation ducts. It comes with a wall plug and screws for installation. This non-return valve can be used universally on all common round ventilation ducts and flexible pipes up to DN150mm. The stainless steel is weather-resistant and corrosion-resistant. The 150mm functional ventilation grille is installed on the outer wall of the exhaust system. When the fan stops, the louvers close automatically, preventing the entry of cold air and the penetration of dirt, insects, and other objects. Due to their ease of movement, the louvers open with very little pressure, which is why they are also called floating louvers. Wide range of uses: Suitable for kitchen hoods, workshops, cellars, tumble dryers, etc. A typical clicking sound may be heard when installed near living areas. Perfect choice for both DIY enthusiasts and professionals. Easy to install using standard tools. Insert the ventilation cover into the ventilation duct or pipe and secure it to the wall with the screws provided. Install the clamping eyelets on the ventilation pipe for optimal retention.
