Broan RDFQF Premium Radiation Damper for QT Series Ventilation Fans NEW
This is a brand new never used in original packaging Broan Premium Radiation Damper for QT Series Ventilation Fans. Damper Model is RDFQF
Many codes require that exhaust fans installed in multi-family fire-rated ceilings must be protected by dampers, which, in case of fire, protect against the spread of heat and flame. Broan offers a variety of radiation/fire damper solutions to meet most any need.
When the air temperature passing through the damper exceeds 165°F the fusible link melts, triggering the thermal fabric to automatically close across the damper. Airflow is interrupted by a flame and heat barrier, preventing the rapid spread of fire to other areas.
