8 inch Aluminum Wall Exhaust Hood Exhaust Vent – Damper – Wire Mesh Screen – Flush Mount – Item #3480MSNT

A damper and wire mesh screen in the 8-inch aluminum wall exhaust hood vent prevent outside elements and air from entering the vent when not in use. The spring-controlled damper opens and allows the exhaust air to exit the vent through the sufficient opening containing the screen, which has a net-free area of 18 square inches. When the screen is removed, the net-free area increases to 34 square inches, allowing for maximum airflow.

Wall Exhaust Vent

The Lambro 8-inch flush mount aluminum exhaust hood vent is for venting through the wall. It features a spring-controlled opening and closing damper that prevents outside elements and air from entering the vent. The damper seals the vent opening when the kitchen, range hood, and microwave are not running because no exhaust air exits the vent. When the appliance operates, the exhaust air pressure pushes the damper open to let the exhaust air escape from the vent.

The exhaust vent can easily be used for new and replacement installations over an existing 8-inch opening. The vent features an opening containing the wire mesh screen with a net-free area of 18 square inches, allowing for less back pressure. When removing the screen, the net-free area of the unrestricted opening is now 34 square inches.

The vent’s manufacturing material is 22 gauge aluminum for durability and will not rust to maintain longevity.

Make sure to check local building codes before installation.
