150mm Stainless Steel Ventilation Grille with Anti-Backdraft Movable Louvers, Automatic Closing, Weatherproof Cooker Hood Grille / Square Dimensions 184x184mm / Stainless Steel Ventilation

The external hood grille serves as an external ventilation grille to cover the ventilation duct. Ready to install with included plugs and screws. The non-return valve can be used universally in all common round ventilation ducts and flexible hoses according to DIN EN 1506. The stainless steel is weather-resistant and corrosion-resistant. FUNCTION: The 150 ventilation grille is mounted on the external wall of the air 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 at very low pressures; therefore, they are also called floating louvers. VERSATILE: Suitable for cooker hoods, workshops, cellars, tumble dryers, and much more. Typical clicking noises may occur when installing near living areas. PERFECT CHOICE for amateurs and professionals. Simple installation with standard tools. Insert the ventilation damper into the ventilation duct or flexible hose and secure it to the wall with the screws provided. Attach the clamping eyelets to the ventilation duct for optimal fixing.
