Broan HD80RDF - 80 CFM 2.5 Sones White Bath Fan
Fix the Broan HD80RDF 80 CFM 2.5 Sones Heavy-Duty Blower in your house to get ample ventilation.
The Broan HD80RDF 80 CFM 2.5 Sones Heavy-Duty Blower features a reinforced fiber thermal fabric, galvanized steel frame and a stainless steel negator type closure spring. The radiation damper attached to the housing protects the openings in 1-, 2-, or 3-hour fire-rated floor-ceiling and roof-ceilings. This blower is Warnock Hersey Listed and can be used in combustible ceilings with ducted fans. The blower has a fusible link that melts when the temperature of air passing through the damper exceeds 165F, resulting in the closure of the thermal fabric across the damper to interrupt the airflow and prevent rapid spread of fire to other areas. You can fix the blower into the housing without removing the damper.
