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:
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.
