Product Details for the NuTone 80RDB

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. Being fire-rated means the ability of a wall, floor/ceiling, or roof/ceiling to withstand the effects of fire for a specified period of time. NuTone ceiling radiation dampers are designed to protect the openings in 1-, 2-, or 3-hour fire-rated floor-ceiling and roof-ceiling designs. When the temperature of the air passing through the damper exceeds 212°F, the fusible link melts and the thermal fabric across the damper closes automatically to interrupt the airflow by becoming a flame and heat barrier, preventing rapid spread of fire to other areas.
  • 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.
  • 212°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.
