The new CD450 and CD450V control dampers from Ruskin are extruded aluminum models that use a 4-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 – are suited for any HVAC application that requires high, energy-efficient performance.
Both models were designed to control and regulate air movement in medium- to high-velocity and pressure HVAC systems. The CD450 and CD450V include airfoil blades with mechanically-fastened blade seals that offer low pressure drop – and less noise – when open and achieve Class 1A leakage (3cfm/ft2 at 1 inch w.g.) performance when closed. Acetyl copolymer blade end caps enhance sealing against finger-style jamb seals.
Additional features add ease during installation and maintenance, and also extend the life of the damper. A telescoping shaft provides up to an eight-inch extension for offset actuator mounting, while a coupler option allows two damper sections to be joined and operated by a single actuator on the outside of the frame. This space-saving option provides a narrower profile in tight areas. The durable designs include positive lock axles and non-corrosive bearings, as well as shake-proof linkage that minimizes service needs.
Ruskin offers the CD450 and CD450V with a five-year product warranty. For more information about the CD450, visit https://www.ruskin.com/model/cd450. For more on the CD450V, visit https://www.ruskin.com/model/cd450v.
