IO Hvac Controls MUA-06 Damper Kit
The iO HVAC Controls MUA-06 is a professional-grade make-up air solution designed to mitigate negative air pressure caused by high-tonnage exhaust systems in residential and light commercial structures. This 6-inch makeup air damper kit features a Power Open/Spring Closed (PO/SC) configuration, ensuring the intake remains sealed when not in operation to prevent unconditioned air infiltration. The system is triggered by an adjustable differential pressure switch with a sensing range of 0.08" to 1.20" WC, allowing for precise calibration based on specific building envelopes and local mechanical codes. Hardwire integration is simplified via the included 24V 20VA transformer, providing a dedicated power source for the actuator without straining existing furnace or air handler control boards. By facilitating controlled ventilation air, the MUA-06 prevents backdrafting of gas-fired appliances and improves overall indoor air quality (IAQ) during heavy exhaust cycles.
Technical Specifications and Benefits
- Code Compliance: Meets IRC requirements for supplemental combustion and makeup air in homes with high-CFM range hoods.
- Differential Pressure Sensing: The included air pressure switch enables automated operation based on actual vacuum conditions rather than simple interlock wiring.
- Robust Construction: Heavy-duty galvanized steel damper blade and housing provide long-term durability in HVAC ductwork.
- Failsafe Operation: Spring-return actuator ensures the damper defaults to a closed position during power loss or system standby.
- Universal Compatibility: Works seamlessly with any exhaust fan or range hood regardless of brand or voltage.
Common Installation Questions
How do you calibrate the pressure switch for this kit?
Contractors should use the adjustment screw on the differential pressure switch to set the activation point just above the dormant static pressure of the house, ensuring the MUA-06 opens only when the exhaust fan creates a significant draw.
Can this damper be used for combustion air intake?
Yes, the iO HVAC Controls MUA-06 is frequently used to provide make-up air for mechanical rooms where gas-fired furnaces or water heaters require specific free-air calculations to prevent rollout.
Where should the pressure probe be located?
For optimal performance, the sensing probe should be installed in a neutral location away from direct supply registers to accurately detect the drop in building static pressure.
