DuroZone Power Open/Power Close Mechanical Three Wire Damper 6" **Normally Ships Same Day**

Description

Three wire, power open, power close damper draws power only when opening or closing, unlike spring return dampers. Use on all zone control applications, works on almost any brand of 24vac zone control panel using two position dampers. Unlike most 3 wire dampers, the Durozone DRD dampers can be used as a slave zone damper (connected directly to a thermostat) without the use of a relay. Requires 3 wires for operation. This is an outstanding choice compared to 2 wire spring return dampers that must pull power, when energized, to overcome the spring. “Normally open or close” does not apply to these dampers since no spring is involved-dampers use power only when moving. *Power open, power close, no spring! *Also see our SD series 3 wire dampers. *Uses power only when moving *Quality construction, 5 year warranty. *24vac low voltage, low power, intermittent operation *15 second open close times. *Full open or close operation only. *3 wires to damper needed for operation *Can be driven directly from thermostat without relay. *Compatible with almost any zone control system using 2 position dampers. PLEASE NOTE: These dampers are manufactured without polyurethane seals, but we will provide them for you to install.
