Resideo MARD-12 Damper
The Resideo MARD-12 Damper is a professional-grade 12-inch round modulating damper designed for high-performance HVAC zoning and bypass control. Built with heavy-duty 22-gauge galvanized steel, this three-wire motorized damper is engineered for longevity in both residential and light commercial mechanical systems. It features a 24Vac floating actuator that provides precise control, with a 90-second motor timing for full stroke transition from open to closed. This power open/power closed damper is ideal for systems exceeding 2000 CFM where maintaining proper static pressure is critical. The MARD-12 includes adjustable range stops for minimum and maximum positions, allowing technicians to fine-tune airflow for static pressure control (SPC) applications or individual zone balancing. Its single-blade design and crimped/uncrimped ends facilitate rapid integration into standard rigid or flexible ductwork.
Key Benefits
- Precision Airflow Control: The floating control actuator allows for incremental positioning, making it perfect for modulating bypass damper setups.
- Durable Construction: The 22-gauge galvanized steel frame and single-blade assembly ensure reliable operation in high-velocity systems.
- Versatile Mounting: Designed for flexibility, the MARD-12 actuator can be oriented on the side or top to accommodate tight mechanical room clearances.
- Broad Compatibility: Seamlessly integrates with Resideo TrueZONE panels and other 24V zoning systems.
- High CFM Capacity: Optimized for systems larger than 5 tons, providing effective bypass air management up to 1200 CFM at .25" W.C.
Common Questions
What is the difference between a MARD and a standard zone damper?
Unlike standard spring-return dampers, the Resideo MARD-12 uses a power open/power closed motor. This three-wire configuration provides consistent torque in both directions and allows for modulating or floating control, which is essential for accurate bypass air management.
Can the motor be replaced without removing the damper from the duct?
Yes, the ML6161 replacement motor is designed for field serviceability, allowing contractors to swap the actuator directly on the MARD-12 assembly if required during maintenance cycles.
Is this damper suitable for high-pressure systems?
The MARD series is rated for systems that do not exceed 2.0 inches W.C. at the damper, making it a robust choice for most light commercial HVAC and large-scale residential applications.
