Vacuum Unit Ejector System Vacuum Pump System Air supply is cut-off when vacuum is reached. Energy saving ejector Air consumption 93% reduction Reduced by the pressure switch for vacuum with energy saving function and efficient ejectors (Under SMC’s measurement conditions) More efficient ejector Suction flow (Compared to other SMC 1-stage ejectors) 50% increase Wiring variations D-sub connector Flat ribbon cable connector Individual wiring

Vacuum Unit ZK2\3A Series Digital pressure switch with energy saving function reduces air consumption by 90%. *1 Under SMC's measurement conditions While the suction signal is ON, the ON/OFF operation of the supply valve is also performed automatically within the set value. More efficient ejector Energy saving ejector Existing product Air is supplied and exhausted intermittently when the vacuum decreases. Air supply j | Air is supplied and exhausted continuously during the adsorption of the workpiece. Air supply^ 1 8 Atmospheric pressure Vacuum pressure Existing ejector Ejector with energy saving...

Vacuum Unit ZK2mA Series Piping Wiring Installation time reduced!! Dual 2-port valve (Supply valve/Release valve) M Supply valve: Self-holding∗1 Even if there is a power cut, the vacuum is maintained as long as there is supply air. q he vacuum is maintained during power failure as long as air is supplied. T This can prevent the workpiece from being dropped. w he unit turns on by instantaneous energizing (minimum 20 ms.). Continuous energizing is not necessary. T This can reduce the power consumption. M Linked supply and release valves operation∗1 The self-holding type supply valve will be turned...
