S & C VOLUME CONTROL DAMPER

J C Cooling LLC multi-leaf volume control dampers have been specifically designed for use in ventilation systems for volume, flow and pressure control in low pressureand light duty applications from low cost. The casing is of sleeve I S &C type whichsuites most of the duct work. The blades are of single skin GI I double skin aerofoilshaped AL* I GI with blade operation parallel* I opposed. The dampers can be fittedwith hand locking quadrant or can be operated by elec- tric or pneumatic actuators. Themaximum size of these VCDs is 500 x 500 mm single module.
