Our products are Made in the USA

A damper in the 4-inch flush mount galvanized steel wall exhaust hood vent prevent outside elements and air from entering the vent when not in use. The damper opens and allows the exhaust air to exit the vent through the sufficient opening which has a net-free area of 20.5 square inches, allowing for maximum airflow.

Dryer Vent

The Lambro 4-inch flush-mount galvanized steel exhaust hood vent is for venting through the wall. It features an opening and closing damper that prevents outside elements and air from entering the vent. The damper seals the vent opening when the clothes dryer and bath fan 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 is for new and replacement installations over an existing 4-inch opening. It features an opening with a net-free area of 20.5 square inches, allowing for less back pressure.

The vent’s manufacturing material is 30 gauge galvanized steel for durability and longevity.

Make sure to check local building codes before installation.
