Galvanized Back-Draft Damper with Rubber Seal

KOM150U back-draft damper is installed in fan exhaust systems to prevent a backdraft of outside air when the fan is turned off. Air pressure opens the damper, which features spring-loaded butterfly damper blades and rubber gasket to ensure minimal leakage in closed position. Easily fits into your vent systems requiring only minimal labor and time. Installing a KOM150U damper reduces energy loss in your home.
