EWC Controls URD-12 Damper
The EWC Controls URD-12 Damper is a professional-grade 12-inch round motorized zone damper engineered for high-performance airflow management in residential and commercial HVAC systems. This power open/power closed damper utilizes a 3-wire floating actuator (MA-ND5) that delivers 18 in/lb of torque, ensuring reliable blade positioning even in high-velocity systems. Constructed from heavy-duty 24-gauge galvanized steel with rolled stiffening beads, the URD-12 is built to handle static pressures up to 1.5" w.c. with minimal leakage. The 24VAC motorized damper features a double-layered blade design integrated with a Poron sealing gasket, providing a tight shut-off to maximize efficiency. Designed for the trade, the unit includes nylon bearings and a Thermo-Tuff drive shaft for silent operation and thermal isolation from the motor.
- Precision Airflow Control: The 3-wire floating actuator allows for granular control and is compatible with most HVAC zone control systems, including high-end communicating panels.
- Visual Diagnostic LEDs: Built-in green (open) and red (closed) LEDs provide immediate confirmation of the damper blade position for easier troubleshooting.
- Field Adjustable: Features adjustable end-stops to set minimum and maximum CFM flow, allowing for precise HVAC air balancing in specific zones.
- Industrial Durability: The single-blade round damper design reduces turbulence and maintains a 650 CFM flow rating at optimal static pressure.
Common Questions
Can this damper be installed in any orientation?
Yes, the EWC URD-12 can be installed at any angle; however, for maximum longevity, it is recommended to avoid mounting the motor at the bottom of the ductwork where moisture or debris could accumulate.
Is the URD-12 compatible with communicating zone panels?
The 3-wire power open/close motor is a standard 24V interface, making it universally compatible with EWC Ultra-Zone panels and many other 24V zoning systems that support floating or 3-wire actuators.
What is the purpose of the 18 in/lb torque rating?
The 18 in/lb torque ensures the actuator has sufficient power to overcome air resistance and seal the Poron gasket against the duct wall, preventing "whistling" and air bypass in high-pressure branches.
