The CD50CE and TED50CE dampers from Ruskin combine the strength of stainless steel and protection of anodized aluminum to combat salt-water elements. The CD50CE is Air Movement and Control Association licensed as Class 1A and meets the IECC. The damper features low-maintenance, non-corrosive bearings and shake-proof linkage; airfoil blades for high-velocity HVAC systems, low pressure drop and quieter performance; and mechanically fastened blade edge seals. The thermal-efficient TED50CE eliminates thermal transfer and the potential for condensation. The damper also meets the IECC, features the same non-corrosive bearings and shake-proof linkage as the CD50CE, and includes twin seals
to ensure no thermal path.
