Description

Static Fire Damper: 1.5, 3 Hour Rated / Multi-Blade / Airfoil Blade Damper Multi-section units can be ordered with a fusible link and locking hand quadrants. 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. NOTE: These options require an actuator to be ordered with the damper.
