Honeywell ZD12X8TZ/U - TrueZone 12" X 8" Parallel Blade Damper

The ZD is a power close and spring open damper. It has a 24V motor used to control circulating air in HVAC systems and used when a normally open damper is required. The ZD is typically used with the TrueZONE and other electronic zoning systems.

  • Mechanical visual position indicator for damper status
  • Solid construction using extruded aluminum frame and blades
  • Parallel blade design for low leakage performance
  • Simple, easy-to-wire, two-wire installation
  • Reliable, strong, 24-volt spring-return motor
  • Fail safe, normally open operation
  • Ordering Instructions: Order ZD (dimension 1) X (dimension 2). Motor is always mounted on dimension 2 side. For example, ZD10x8 is a 10" X 8" damper with the motor on the 8" side; but a ZD8x10 is an 8" X 10" damper that has the motor on the 10" side
  • Damper can be installed in any orientation. The mounting side can be on either the bottom or the side of the duct
