Honeywell ZD Series Dampers Are Power Close, Spring Open Dampers With 24-Volt Spring-Return Motors That Control Circulating Air In Heating, Cooling And Ventilation Systems.
For use when a fail-safe, normally-open damper is required. Works with TrueZONE systems and other electronic zoning systems. Adjustable minimum and maximum range stops allow you to adjust damper to meet your individual needs. Solid construction using extruded aluminum frame and blades. Quiet operation with fewer blades. Parallel blade design for low leakage performance. DuPont KEVLAR® gearing reduces wear, more than doubling damper life. Simple, easy-to-wire two-wire operation and easy slip-in design. Can be mounted on the side or bottom of the duct.
