AEROVAC –VCD – AV – 11– G –GD–F High Performance Control Dampers combine the performance of an Galvanized steel airfoil blade with the rugged durability of a steel frame. They offer unsurpassed Class 1 leakage and pressure drop characteristics for superior performance that meets the International Energy Conservation Code maximum leakage criteria for building envelope dampers. Leakage rating is maintained with airflow in either direction, permitting right or left-hand drive installation. Suitable for use in high velocity, medium pressure commercial and industrial HVAC systems.
Standard features include heavy duty Galvanized airfoil blades that combine superior rigidity and deflection resistance with low pressure drop, a 16 ga. (1.6) galvanized steel hat channel frame with die-formed corner gussets for superior structural strength, a no-maintenance concealed linkage enclosed in the side frame out of the air stream for reduced pressure drop. A comprehensive selection of options are available to meet specific installation requirements and a variety of electric or pneumatic actuators are available for factory or field mounting.
Frame: 20-16 ga. galvanized steel hat channel with die-formed corner gussets.
Blades : 6″ (152mm) wide. 24 ga. (0.7) galvanized steel formed into an aerofoil cross-section. Equivalent Thickness: 17 ga. (1.4) with Parallel or opposed action.
