Model VPU VACUUM SYSTEMVPU-E10VPU-D20�E�Application�E�A vacuum system dedicated to the vacuum chucks. The shuck side is evacuated continuouslyin order to eff ectively maintain atmospheric pressure on the workpiece on the chuck work face.Note that this system must not be modifi ed to a pressure container.�E�Features�E�●A vacuum evacuation system, fi lter, vacuum tank and vacuum gage are incorporated neatly.●Suction and evacuation operations to mount and demount workpieces can be done quicklyand easily with the attached special operating handle.●A diff erence in pressure over 80 kPa (600 mmHg) can be obtained continuously.■Ejector type VPU-EA vacuum system to reduce pressure by jetting air at high pressure (principle of the spray gun).This is recommended where an air line by use of a compressor is installed. This type can beused for both wet and dry machining operations. However, the use of a lubricator in the air linemust be avoided.■Dry pump type VPU-DA vacuum system to reduce pressure by evacuation by a pump driven by a motor. A powersource only is required to obtain an independent vacuum source. Note, however, this isrecommended only for dry machining operations.■Other typesIf the physical contact with the bottom face of workpieces is poor, a large amount of air leaks,requiring a large evacuation amount. In such a case, a blower type is required for dryoperations and a water-sealed vacuum pump is required for wet operations depending on workconditions.

Satisfactory functions!�E�Application�E�A vacuum system dedicated to the grid seal type vacuum chucks.�E�Features�E�●The vacuum tank has been eliminated to make a very compact size compared with the conventional model(VPU-E10). This system can be handled easily.●A function to check the vacuum status is incorporated.●This is for dry operation.●Auxiliary functions in consideration of operating status and safety are incorporated. (Vacuum adjustment,interlock with the machine via vacuum check output signals, etc.)�E�Application�E�An option to facilitate the use of vacuum chucks.�E�Features�E�●The operating valve and the vacuum gage have beenintegrated to enable it to check the state of workpieceholding near the chuck.●By changing the location of the blank cap, a position tomount the vacuum gage can be selected from three places.VPU-EGVPU-OVModel EvacuationVolumeContinuous PressureDiff erence Suction PortCompressed Air DimensionsMassPressure Consumption Supply port Out. dia.
