The Festo VAD Series Vacuum Generator features a single-stage design and operates according to the Venturi principle. The different performance classes of the individual product series makes it possible to select vacuum generators tailored to suit the specific requirements of each application.

Compressed air flowing from ports 1 to 3 generates a vacuum at port 2 in accordance with the ejector principle. The low exhaust noise during blowing can be further dampened by using a silencer in port 3. Workpieces can be picked 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. 32cm3 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.
