Model FSD-182-OP

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

The FSD-182-OP combination fire smoke damper employs triple-V 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 fire 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 from the face of the damper through the HVAC grille. The FSD-182-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.
