The ND Damper is constructed using Heavy Duty 0.80†extruded aluminum. Nylon Bearings for quiet operation. Overlapping parallel blade design. Reliable operation up to 1.5â€wc and 1500FPM duct velocities. The UL Listed Motor Actuator. 24vac 3 wire power open/power close or floating function. The motor actuator is rated at 18â€lbs. of torque. Superior to low torque Spring type motors. The Motor Actuator housing is rated NEMA1. Integrated End-Stop Adjustment allows a percentage of Relief Air (Leakage) when the damper is powered closed. You may set a maximum open position as well, which is useful during test and balancing procedures. Bright green and red LED's Indicate damper open and closed position.
