BROAN-NuTone FIN-6MD Damper
The Broan-NuTone FIN-6MD is a precision-engineered 6-inch motorized supply damper designed for integration into fresh air ventilation systems and HVAC makeup air applications. This 24VAC automatic damper features a normally closed configuration, ensuring a tight seal against outside air infiltration when the system is inactive. Built with a heavy-duty galvanized steel housing, the FIN-6MD provides long-term durability in light commercial and residential mechanical rooms. The synchronous motor enables controlled damper actuation for localized IAQ management, allowing contractors to meet ASHRAE 62.2 ventilation standards effectively. Designed for seamless installation within rigid or flexible ductwork, this motorized damper features secure ribbing for leak-proof connections. Whether used for combustion air intake or balanced ventilation, the FIN-6MD delivers reliable airflow regulation and minimizes thermal bridging when properly insulated. This HVAC zone damper is a critical component for technicians optimizing pressurization and outdoor air supply cycles.
Key Benefits
- 6-inch diameter galvanized steel construction ensures rigid duct compatibility and corrosion resistance.
- 24V motor operation allows for simplified wiring into standard HVAC control boards or external transformers.
- Normally closed logic prevents unwanted drafts and energy loss during standby periods.
- Gasketed blade design minimizes air leakage and improves overall static pressure management.
- Compact footprint facilitates installation in tight inline duct configurations common in retrofit applications.
Common Questions
How do I wire the FIN-6MD to a furnace control board?
The unit utilizes a standard two-wire 24VAC lead; it is typically wired to the 'C' and 'Y' or 'G' terminals depending on whether you require ventilation during cooling or continuous fan cycles.
Can this damper be mounted in any orientation?
Yes, the synchronous motor and spring-return mechanism allow the FIN-6MD to operate effectively in vertical or horizontal duct runs.
Is the motor replaceable if it fails?
The motor assembly is designed for heavy-duty cycles, but the standard design allows for serviceability or replacement without removing the entire damper housing from the ductwork.
