This ND Series rectangular motorized damper simplifies HVAC zoning installations. Built with heavy-duty 0.80" extruded aluminum and quiet nylon bearings, it ensures durability and minimal noise. The overlapping parallel blade design provides low leakage, enhancing system efficiency. It operates reliably at static pressures up to 1.5" w.c. and duct velocities up to 1500 FPM.The damper features a robust 24V, 3-wire power-open/power-close motor actuator delivering 18 in-lbs of torque. Integrated diagnostic LEDs clearly indicate open and closed positions, aiding setup and troubleshooting. Adjustable end stops allow for setting minimum airflow (leakage) when closed or limiting the maximum open position for balancing purposes.
