  • 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

  • IN YOUR 80 RDF WHAT IS THE MAXIMUM LENGH THAT THE DUCT CAN BE INCLUDING ELBOWS

    Asked by: Anonymous
    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.
