Insulated Low Leak Commercial Control Damper CD40X2
The CD40x2 has an 8" frame and aluminum construction. It features:
The lowest leakage attainable--6 cfm/sq. ft. at 4" w.g.
Airfoil blades, which have greater strength, produce less sound, greater sealing ability, and static pressure loss.
The most effective method of energy-saving insulation. Testing has proved that the CD40x2 insulated more efficiently than conventionally insulated blades.
Unique double edge blade seal design that enables higher pressure on either side of the damper to assist in blade to blade seal shutoff
Linkage concealed out of the airstream for low maintenance and reduced air turbulence
