Product Description
Lambro Industries - 344 The Lambro 4-inch aluminum exhaust hood vent with 11-inch pipe 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 26 gauge aluminum for durability and will not rust to maintain longevity.
Make sure to check local building codes before installation.
