Overview
NCA offers several options for extruded aluminum control dampers for more corrosive environments and applications. The ACD (Aluminum Control Damper) is offered in a few different configurations of frame and blade widths in order to cover every application possible. The two numbers after the model string “ACD” represent the frame width (in inches) followed by the blade width (in inches) in that order. NCA also manufactures options for thermally insulating (see model ACD-56-I) as well as thermally broken (see models TBD) control dampers.
