SVA

■ VACUUM CHUCK

Features
● Instantly suck and fix a workpiece with air from a compressor.
Working with processing machines such as machining centers or
abrasive machines.
● As a vacuum ejector is equipped, no vacuum pump is required.
● Easy start just by connecting tube for one-touch valve to a
compressor in your factory.
● Air suction is ideal for non-magnetic materials such as stainless
steel, aluminum or resin.
● When the valve is off, a small quantity of air flows out of a 1mm
diameter vacuum hole to prevent any foreign material from
entering the air circuit.
● As most of the parts are behind the front panel, maintenance

and part replacement are easy.
SVA2025 ● The built-in pressure reduction valve allows an economical use
saving air consumption and valve adjustment.
● It is possible to combine 2 units thanks to the holes for hexagon
bolts at both sides of each unit.
＊ Use solid clamps (see P.246) to fix the workpiece to a machine
