Atmosphere’s all new galvanized steel back draft dampers fit directly into the duct simplifying installation. They feature a shaft for each of the 2 flaps so to prevent jamming. Also, the flaps close onto a perimeter gasket ensuring the best air seal and quiet operation.
The Damper is a sensational customer favorite, and we hope you like it just as much.
