The patent-pending Barometric Zone Damper™ (BZD) works like any standard damper with one exception: It has a built-in barometric relief mechanism that eliminates the need for a bypass damper, says the company. The damper has been designed with both a fixed and a hinged blade and is controlled by an actuator.
