Abstract:
An improved butterfly damper for air delivery systems, having multiple rotatable blades, and a centrally located blade rotating, or actuation means. Each blade comprises an offset, or displaced portion to allow concealment of the actuation mechanism upon closure. This offset portion allows the blades, upon closure, to meet and form a seal around the least complex portion of the actuation mechanism.
