Ruskin’s new CD450 and CD450V control dampers are designed for commercial buildings with medium- to high-velocity HVAC systems. The extruded aluminum models use a four-inch-wide frame design with finger-style jamb seals for a light-tight sealing effect.
The CD450 and CD450V, which have horizontal and vertical blade orientations, respectively, include airfoil blades with mechanically fastened blade seals. Acetyl copolymer blade end caps enhance sealing against finger-style jamb seals. A telescoping shaft provides up to an eight-inch extension to offset actuator mounting, while the coupler option allows two damper sections to be joined and operated by a single actuator on the outside of the frame.
