Durozone 18 inch Round HVAC motorized air damper dampner 3 wire 24V AC

Description

Durozone RD 18 (eighteen)  inch round damper with 24volts AC, 3 wire power close/power open damper. (Picture shown is 10 inch all others similar)  One of the oldest and most proven designs in the motorized damper business, the Durozone RD damper is an outstanding value and features a 3 wire, power open, power close motor.  Unlike spring return dampers, the  3 wire design only uses power when the damper is moving.
Still, the Durozone RD damper series can be controlled by a standard thermostat with no extra relay needed, as is common with some 3 wire dampers.  A 5 year Warranty is standard with this damper.  Check our pictures:  blades riveted (not spot welded) with heavy duty construction throughout.  Compatible with virtually any 24vac Zone control system or thermostat.
