ABSTRACT:
An apparatus for controlling the mixing of atmospheric air with return air from a building. The apparatus has a housing that includes a base baffle and a roof baffle disposed therein. A damper is pivotally secured to the base baffle, and another damper is pivotally secured to the roof baffle. The two dampers are interconnected pivotally by a damper linkage such that when the first damper is caused to be pivoted on and about the base baffle, the other damper pivots on and about the roof baffle. An actuator is provided such as to be supported by the base. The actuator pivotally connects to the damper that pivotally connects to the base baffle such that when the actuator is actuated, the damper that pivotally connects to the base baffle is caused to be pivoted on and about the same. A method for controlling the mixing of atmospheric air with return air from a building.
