Model FSD-151-OP

1-1/2 Hour - Combination Fire Smoke Damper
Airfoil Blade - Out-of-Partition

The FSD-151-OP combination fire smoke damper employs airfoil blades for point-of-origin control of fire and smoke in static and dynamic smoke management systems. These specialty dampers are approved for installation with the closed plane of the blades up to 14-1/2" (368) outside the fire rated partition and come standard with the actuator in the airstream allowing for direct service access fromThe FSD-151-OP is qualified to 4,000 ft/min (20.3 m/s) and 8 in.wg. (2.0 kPa) and may be installed in vertical walls or partitions, or horizontally in floors or assemblies with fire resistance ratings up to 2 hours.
