The BZD Barometric Zone Damper™ is a major breakthrough in zoning. With the BZD, no bypass is required! Cut zoning system costs, use less installation space, and increase system efficiency up to 20%. The BZD Barometric Zone Damper™ operates like any standard zone control damper but has a built-in static pressure relief mechanism that eliminates the need for a bypass damper. It also comes factory set and does not require any adjustments.
