ABSTRACT:
A barometric damper has a housing which is adapted to be coupled with a structure. The housing has an opening that allows spatial communication between the interior and the exterior of the structure. The damper also has a damper blade. The damper blade is movably coupled with the housing. The blade has an open position where the blade accommodates air passage through the opening and a closed position where the flow of air through the opening is substantially precluded. The damper also has a lever that is movably coupled with the housing. The lever has an attaching means that is used to attach the lever to the blade when desired. The lever is movable between a first position where the lever accommodates free movement of the blade in response to barometric pressure changes on opposite sides of the blade, and a second position where the lever maintains the attaching means against the blade, thus holding the blade in its closed position.
