EWC Controls ND-24X10 Damper

EWC Controls ND-24X10 Damper

The EWC Controls ND-24X10 Damper is a professional-grade rectangular zone damper engineered for high-performance HVAC zoning systems. Constructed from 0.080" heavy-duty extruded aluminum, this 24" wide by 10" high unit features parallel blade technology to ensure minimal air leakage and maximum structural integrity. The 3-wire floating actuator is side-mounted on the 10" dimension, operating on 24Vac with a reliable power open and power closed mechanism. This design eliminates the reliability issues often associated with spring-return motors by utilizing 18 in-lbs of motor torque to drive the blades. The ND series damper is designed to handle static pressures up to 1.5" W.C. and includes integrated nylon bearings for quiet, maintenance-free operation. For the technician, the terminal block connections and visual LED indicators simplify the commissioning process, while the adjustable end-stops allow for precise minimum position airflow settings to meet specific ventilation requirements.

Key Benefits
  • Heavy-Duty Construction: Built with 0.080" extruded aluminum to prevent frame distortion in high-velocity ductwork.
  • Low Leakage Design: Overlapping parallel blades provide a 97% seal, optimizing airflow control across Ultra-Zone systems.
  • Precision Actuation: The 3-wire motor prevents the aggressive "slamming" common in 2-wire setups, extending the life of the gear train.
  • Quiet Operation: Glass-filled nylon bearings eliminate metal-on-metal contact, significantly reducing noise during zone transitions.
  • Visual Diagnostics: Built-in green and red LEDs provide immediate feedback on the current damper position for faster troubleshooting.
Common Questions

Is this damper compatible with standard 24V zone control panels?
Yes, the ND-24X10 is compatible with most 24Vac 3-wire zoning controllers. It functions as a power open/power closed device, requiring a common wire and two hot legs for directional control.

Can the motor be moved to the 24" side if needed?
On this specific model, the actuator is factory-mounted on the 10" side. To ensure proper torque distribution and blade alignment, it is recommended to install the unit in the orientation specified for the second dimension provided.

How do I adjust the minimum air bypass?
The actuator includes an integrated end-stop adjustment bolt. By adjusting this stop, you can prevent the blades from closing fully, allowing a specific percentage of relief air to pass through the zone when the damper is "closed."
