ABSTRACT:
A multiple bladed air damper unit for heating, ventilating and air conditioning systems includes separate and individual end edge seal elements sealing off the end edges to the frame in the closed position. The seal elements are mounted in end-to-end relation and define an essential continuous flat sealing surface in opposed, abutting alignment with the individual flat planar end edges of the blades. Each seal element is a thin, spring-like resilient metal plate of a length essentially identical to that of the end edge of the blades. The metal seal element has a crowned cross-section defining a central, generally flat seal portion integrally interconnected by inclined walls to mounting edges. A central opening is provided for the blade pivot shaft. The element is compressed between the end of an aligned blade and the damper frame to establish a resilient, sliding engagement between the blade and flat seal portion. The element includes an end tab which extends into the channel portions and the tab has an integral inwardly struck-out lip. The tab extends through an opening in the frame to prevent rotating of the element and to loosely hold the seal element in place during assembly.
