Back Draft Damper, Aluminum

The Maxam ABD10 Aluminum Back Draft Damper is a sturdily constructed aluminum blade-type damper with a non-twist channel steel frame requiring no external support. The Maxam ABD10 Damper features bronze oilite bearings which permit free, smooth operation. The damper also features blades which are set back from the vertical line to ensure positive closure and also to prevent the rain from entering. The bottom of the blades are furnished with a urethane gasket in order to eliminate air leakage and to ensure quiet closure. The linkage of the Aluminum Back Draft Damper is constructed from heavy gauge aluminum.
