High-performance Control Damper Extruded Aluminum | Vertical Airfoil Blade Class 1A Leakage CD450V

The High-Performing Ruskin Model CD450V is designed to control and regulate air movement in medium to high velocity and pressure HVAC Systems. The CD450V has extruded aluminum vertical airfoil shape blades which offers low pressure drop when open and meets AMCA Class 1A Leakage when closed. Manual, electric or pneumatic actuators are applied to operate the damper open and closed. CD450V meets the leakage requirements of the of the International Energy Conservation Code (IECC).
