Commercial Control Damper CD40

The CD40 has a 4" frame and aluminum construction. It features:

• Airfoil blades, which have greater strength, produce less sound, greater sealing ability, and static pressure loss
• The ability to easily butt to the back side of a louver for tight shut-off capability
• 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
