FlexDamper™ Ceiling Radiation Damper

FlexDamper is an all-in-one, flexible radiation damper for combustible and non-combustible assemblies. Panasonic’s next generation FlexDamper addresses the change in UL and Warnock-Hersey’s standard testing protocol:

  • UL555C, no longer automatically certifies both Combustible (Wood Joist/Wood Truss) and Non-Combustible (Steel Beams/Girders/Trusses) by meeting the 1 - 3 Hour 555C Rating
  • UL and Warnock-Hersey (UL/WH) now require a separate Fire Chamber Fire Test to verify the efficacy of the Ventilation Fan/Radiation Damper in a Wood Truss Assembly

FlexDamper meets UL Combustible Assembly Ratings for 'Stick-Built' low or mid-rise Multi-Family or Hotel/Lodging projects, and offers the best option for Architect/Engineer projects due to the flexibility to be able to use any 10 ¼" fan for Fire-Rated projects. It allows for two-stage project installation to protect fan/motor during drywall/interiors construction phase and allows easy access or replacement of the fan/motor.

FlexDamper Features:

  • Folded ceramic curtain style damper to meet both Combustible and Non-Combustible UL Assemblies
  • Allows for two-stage construction; fan housing and damper sleeve during framing, fan/motor/damper installation after finishes
  • Easy access to fan/motor/damper for maintenance
  • Compatible with most Panasonic 10 1/4" 50 – 150 CFM fans, fan/lights and fans with motion sensor
  • Galvanized steel frame with 165°F fusible link
  • High temperature, non-asbestos, reinforced fiber thermal fabric damper
