Ratings and installation types may vary with construction.  Please review submittals and installation instructions prior to application.

1.5, 3 Hour Rated / Multi-Blade / 3V Blade Dynamic Fire Damper

The FDD-MB-3V has been designed and tested to exceed all UL, ULC and NFPA requirements.  Its rigid frame and integrally braced corner provide true damper alignment that generally resists being installed out of square or out of flat, ensuring performance equal to test results.

Multi-section units must be ordered with an actuator and a single heat responsive device, except as noted.

Single-section units can be ordered with a fusible link and locking hand quadrant.

Options EFL (Electric Fusible Link) and PFV (Pneumatic Fusible Valve) are also available to provide quick and economical ways to check damper operations and provide a Systematic Closure Control. The PFV option allows damper operation without the need/cost for an EP valve and electrical connection at the damper.
