FlexDamper® Ceiling Radiation Damper

The 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. 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.

Approved for Combustible & Non-Combustible Assemblies:

Combustible: UL 555C listed for use in a one hour: fire-rated, wood truss floor/ceiling and roof/ceiling designs; UL 555C classification for the following one hour UL Wood Truss Assembly Ratings: L521, L528, L546, L558, L562, L574, L576, L581, L583, L585, M509; P522, P-533, P-538, P-545 and P-548.
