The EWC Controls ND Series Motorized Damper is built with heavy-duty extruded aluminum and features nylon bearings for quiet operation. Its overlapping parallel blade design ensures low leakage (less than 5%) at static pressures up to 1.5" w.c.This damper utilizes a power open/power close, 24VAC/VDC motor actuator rated at 18 in-lbs of torque, housed in a NEMA1 enclosure. Integrated end-stop adjustments allow for setting minimum closed and maximum open positions for airflow balancing. Bright LEDs provide clear visual indication of the damper's open or closed status.
