Application

The FSD-141-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 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 from the face of the damper through the HVAC grille.
