The ND Damper is constructed using Heavy Duty 0.80 extruded aluminum.

Nylon Bearings for quiet operation.

Overlapping parallel blade design insures low leakage.

Designed to operate at static pressures up to 1.5 w.c.

The UL Listed Motor Actuator is a 24 vac 3 wire power open/ power close type.

The motor actuator is rated at 18lbs. of torque. Superior to low torque Spring type motors.

The Motor Actuator housing has a NEMA1 Rating.

Integrated End-Stop Adjustment allows for a percentage of Relief Air (Leakage) to be set when the damper is powered to closed and/or you may set a maximum open position as well.

Bright green and red LEDs Indicate damper open and closed position.
