6 In. Aluminum Duct Wall Cap With Spring
lambro 6 in. aluminum duct wall cap with spring - Description
The Lambro 6-inch aluminum exhaust hood vent with a 3-inch pipe 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 and 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 6-inch opening. The vent features an opening containing the 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 vents manufacturing material is 22 gauge aluminum for durability and will not rust to maintain longevity. Make sure to check local building codes before installation.
