Company: Ruskin
Product: TED40x2
Description: The low-leakage insulated control damper features insulated airfoil blades, which offer great strength, produce minimal sound, provide sealing ability, and reduce static pressure loss. It has an 8-inch frame and aluminum construction. When closed, the damper traps a minimum 4 inches of dead air space between the double-blade assembly. Additionally, a thermal break between frame sections prevents heat transmission through the frame, and the blade cavities are filled with urethane foam. The damper’s unique double-edge blade seal design enables higher pressure on either side to assist in blade-to-blade seal shutoff. Seals are mechanically locked in extruded blade slots but can be easily replaced in the field. The TED40x2 also features linkage concealed out of the airstream for low maintenance and reduced air turbulence.
