GRANDVIEW, Mo. —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 ideal 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 (3 cfm per square foot at 1-inch w.g.) performance when closed. Acetyl copolymer blade end caps enhance sealing against finger-style jamb seals.
