Product Description
Lambro Industries - 109R The Lambro aluminum exhaust hood vent is ideal for venting through the roof. The damper seals the vent opening when the bath fan, 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 4-inch round opening. The vent features an opening containing the screen with a net-free area of 10.5 square inches, allowing for less back pressure. When the screen is removed, the net-free area of the unrestricted opening is now 20 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.
