TRIMEC, we look forward to your visit. Don't hesitate to contact us if you have any questions.✨ The external vent cover serves as an external ventilation grille, covering ventilation ducts. Supplied with wall plugs and screws for installation. This non-return valve can be used universally on all standard round ventilation ducts and flexible hoses up to DN150MM. 19*19*8 (overall size). The stainless steel is weather and corrosion resistant. The functional ventilation grille 150 is installed on the exterior wall of the exhaust system. When the fans stop, 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; this is why they are also called floating louvers. Wide range of uses: Suitable for kitchen hoods, workshops, cellars, dryers, etc. A typical clicking noise should be heard when installed near living areas. Perfect choice for amateurs and professionals. Easy to install using standard tools. Insert the vent cover into the vent duct or pipe and secure it to the wall with the provided screws. Install the clamping eyelets on the vent pipe for optimal retention. Note: All measurements are taken manually; please allow for a 1-3 cm error due to differences in lighting and display.
