Barometric Zone DamperThe Barometric Zone Damper (BZD) works like any standard zone damper with one exception — it has a built-in static pressure relief mechanism that eliminates the need for a bypass damper. Unlike a standard zone damper, the BZD has been designed with both a fixed and a barometric hinged blade that are controlled by an actuator. The BZD requires no adjustment, reduces labor, and cuts system cost.
