  • Many local codes require that exhaust fans installed in 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.
    • Housings and finishes (motor assembly and grille) sold separately in units of four per carton - purchase housings for rough-in and blower assemblies/grilles later for finishing
    • UL classified (UL standard 555C) for use in 1-, 2-, or 3-hour fire-rated floor-ceiling and roof-ceiling designs
    • Warnock Hersey Listing allows use in combustible ceilings with ducted fans
    • High temperature, non-asbestos, reinforced fiber thermal fabric
    • Galvanized steel frame
    • 165°F fusible link
    • Stainless steel negator-type closure spring
    • Available from 50 CFM to 110 CFM
    • Radiation damper comes attached to housing
    • Blower assembly will fit into housing without the removal of the radiation damper - one less step in installation process

    Answer: 
    Thank you for your question on the model 80RDF, 80 CFM finish pack. Using four inch rigid duct work, our 80 CFM fans can handle up to 23 feet of straight duct work. You would need to reduce that distance by four feet for every elbow.
