Vacuum generators with sturdy aluminium housing for direct connection of a suction cup. • Compressed air flowing from 1 to 3 generates a vacuum at port 2 in accordance with the ejector principle. • The low exhaust air noise during blowing can be further dampened by using a silencer in port 3. • Workpieces can bepicked up in any position.When the compressed air is switched off, suction stops and the vacuum breaks down. • During suction with vacuum generator VAK, a volume of approx. 32 cubic centimetres is filled with compressed air. This creates an ejector pulse when the input pressure is switched off, reliably releasing the workpiece from the suction cup. • Max. switching frequency approx. 10 Hz at 6 bar and with approx. 1 m of suction line.
