RenewAire Motorized Damper – 6″ or 8″

RenewAire Motorized Damper – 6″ or 8″ Automatic Airflow Control for ERVs The RenewAire Motorized Damper provides dependable, automatic airflow control for energy recovery ventilator (ERV) systems. Available in 6-inch and 8-inch diameter options, this motorized damper helps prevent unwanted airflow when ventilation is off—protecting indoor air quality, improving energy efficiency, and supporting code compliance in residential and light commercial applications. Designed to Protect Indoor Air Quality During adverse outdoor air conditions—such as wildfire smoke events—or when ventilation is not required, uncontrolled airflow can compromise indoor air quality. The RenewAire Motorized Damper automatically closes when the ERV is off, helping block outdoor contaminants from entering the building. As a result, occupants benefit from better air quality and improved comfort. Meets ENERGY STAR® Program Requirements Both ENERGY STAR® Single-Family New Homes and ENERGY STAR Multifamily New Construction programs require a motorized damper on the ERV supply airstream when connected to a ducted HVAC return. When installed according to RenewAire’s MD Series guidelines, the 6″ and 8″ motorized dampers meet this requirement by restricting airflow during ventilation off-cycles and occupant overrides. Consequently, builders and contractors can achieve compliance with confidence. Fast Installation with Long-Term Reliability Installation is quick and straightforward. Each damper fits directly onto round ERV duct collars, reducing labor time and simplifying setup. Additionally, the floating motor mount ensures precise alignment between the motor, shaft, and damper blade. This design prevents binding and reduces wear over time. Moreover, the clutch/coupler mechanism minimizes moving parts, which improves reliability and extends service life. The adjustable flow-control feature allows installers to limit how far the damper blade opens or closes, offering added flexibility for specific system requirements. Durable, Fail-Safe Construction Constructed from corrosion-resistant galvanized steel, the RenewAire Motorized Damper is designed for indoor ductwork applications only. The damper operates in a normally closed, spring-return mode, ensuring airflow is safely blocked during power loss or system shutdown—an essential fail-safe feature for ventilation systems.
