Ruskin model CD60 incorporates an exclusive one-piece steel frame construction, making it the engineer’s preferred frame design with no fasteners required. Frame corners are internally braced and machine staked. Exclusive one-piece aerodynamic dual skin airfoil blades are suitable for medium and high pressure velocity applications. Blade edge seals are mechanically fastened to ensure years of sustainable performance and reliability. Frame and blade construction, in concert with compression type chambered jamb seals, ensures leakage performance on par with requirements of
the International Energy Conservation Code (IECC). Factory mounted and commissioned actuators are among the available options.
