Abstract
The present invention relates to a device for automatically controlling exhaust flow to a ventilated rack of animal cages when an air inlet system, such as an air supply blower, to the rack is not operating. Accordingly, the device can be used in a system that assures that the ventilation system is balanced when one or more of the ventilated racks are removed from their respective air supplies. The device includes a damper housing that is adapted to be connected between an exhaust outlet of the ventilated rack and an exhaust system. A movable damper is positioned within the damper housing and is moveable between an open position and a closed position. In the closed position, the device creates a partial obstruction to air flow in the connection.
