Resideo MARD-6 Damper
The Resideo MARD-6 is a heavy-duty 6-inch modulating automatic round damper designed for high-performance bypass control and zoning applications. Constructed from 22-gauge galvanized steel, this unit is built to manage the higher static pressures common in larger residential and light commercial systems, particularly those exceeding 5 tons. The integrated three-wire floating actuator provides 90-second timing from open to closed, delivering granular control over airflow without the sudden pressure spikes associated with rapid-cycling dampers. When utilized for bypass, the MARD-6 pairs with a static pressure controller to maintain balanced duct velocity, preventing freeze-ups and high-limit trips. It features a male crimped end and an uncrimped female end for seamless integration with rigid or flexible ductwork. For field flexibility, the damper can be mounted in any orientation—horizontal or vertical—provided the motor is positioned on the top or side to ensure mechanical longevity.
Key Benefits for HVAC Professionals
- Precision Airflow Management: The modulating floating actuator allows for incremental positioning, making it ideal for modulating bypass and multi-stage zone logic.
- Industrial-Grade Construction: The 22-gauge galvanized steel shell resists bowing and ensures reliable blade seating even under a maximum differential pressure of 2.0 in. W.C.
- Simplified Wiring: A three-wire 24Vac configuration (M1 Common, M4 Open, M6 Close) ensures compatibility with most modern zone control panels and static pressure switches.
- Optimized Velocity Control: Rated for a bypass capacity of 200 CFM, this 6-inch model is critical for maintaining correct static pressure in smaller zones.
Common Questions
Can this damper be used as a replacement for older Honeywell ML6161 motors?
Current MARD-6 units often feature the LMB24-3-T FLU actuator. If your existing setup uses the older ML6161B2024, ensure the anti-rotation shaft alignment matches, as the newer actuators require a compatible mounting bracket tab.
Is it normal for the motor to feel warm during operation?
Yes, the 24V motor is designed for continuous duty in zoning applications. However, verify the three-wire floating control is receiving the correct signals from the zone panel to prevent unnecessary stall current.
Does this damper require a specific mounting orientation?
While the MARD-6 can be installed in vertical or horizontal duct runs, technicians should always mount it so the actuator is on the side or top to prevent moisture or debris from affecting the drive gears.
