Lambro 109NS 4 Inch Aluminum Roof Exhaust Vent – Damper – No Screen – 1.75 Inch Pipe

Product Overview

The Lambro aluminum exhaust hood vent is ideal for venting through the roof. The damper seals the vent opening when the clothes dryer, 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 with a net-free area of 20 square inches, allowing for less back pressure.

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.
