SKC-C - Madel

SKC-C C circular constant air volume dampersMADEL The SKC-C series dampers are designed to facilitate balancing ofventilation systems. Damper suitable for circular duct mounting.Those dampers maintain the constant air volume at varying pressures,caused by connection and disconnection of system parts, clogging offilters and ducts, wind effects, window opening etc.SKC-C is an automatic damper independent of external energy sources.This operation is based on the balance of forces on the blade betweenthe air pressure and the reactive forces that exert a spring and ainflatable damper.The adjustment knob has a graduated rate scale allows quick and easyadjustment of the desired air flow. Each nominal size damper allows aselection of flow with a ratio Vmax Vmin 3:1.1 06/13
