® has introduced the CD50IF, the newest addition to the airfoil blade models. The CD50IF is a low leak, extruded aluminum damper with integral flange designed with airfoil blades for higher velocity and pressure HVAC systems.

It meets the leakage requirements of the International Energy Conservation Code by leaking less than 3 cfm/sq. ft. at 1” of static pressure and is AMCA licensed as a Class 1A damper. The CD50IF complements the current extruded aluminium model the CD50.


AMCA Class IA leakage rated for energy savings
Airfoil blades for low pressure drop and less noise
6063T6 high yield extruded aluminium for low maintenance
