150mm Stainless Steel Ventilation Grille with Anti-Backdraft Protection, Movable Blades, Automatic Closing, for Cooker Hoods, Weatherproof, 184x184mm

The outer grille of the hood serves as an external ventilation grille, covering the ventilation ducts. Supplied with wall plugs and screws for installation. This non-return valve can be used universally on all ventilation ducts: standard round and flexible pipes up to DN150mm. The stainless steel is weather-resistant and corrosion-resistant. The DN150 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 noise may be heard when installed near living areas. Perfect choice for both hobbyists and professionals. Easy to install using standard tools. Insert the vent cover into the ventilation duct or pipe and secure it to the wall with the provided screws. Install the clamping eyelets on the ventilation duct for optimal retention. Note: All measurements are taken manually. Please allow for a 1-3 cm error due to differences in lighting and display settings. There may be slight color variations; please refer to the actual item received.
