FD-150:
The FD-150 fire damper employs airfoil blades for point-of-origin control of fire in static and dynamic HVAC systems. The FD-150 is qualified to 3,000 ft/min (15.3 m/s) and 4 in.wg. (1.0 kPa) and may be installed in vertical walls or partitions, or horizontally in floors or assemblies with fire resistance ratings up to 2 hours.
FD-150-OP:
The FD-150-OP fire damper employs airfoil blades for point-of-origin control of fire in static and dynamic HVAC 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 allow for direct service access from the face of the damper through the HVAC grille. The FD-150-OP is qualified to 3,000 ft/min (15.3 m/s) and 4 in.wg. (1.0 kPa) and may be installed in vertical walls or partitions, or horizontally in floors or assemblies with fire resistance ratings up to 2 hours.
