Venturi principle

Operating principle

Pneumatic vacuum generators function based on the Venturi principle
Compressed air is introduced into the ejector (A)
Due to the reduced cross-section of the motive nozzle (the Venturi nozzle [B]), the compressed air is accelerated. The dynamic pressure increases, while the static air pressure simultaneously decreases
Once it has passed the motive nozzle, the accelerated air expands and a vacuum is generated
Air is “sucked” through the vacuum connection (D) into the ejector
The compressed air escapes from the ejector through the silencer (C) together with the “sucked-in” air.

Advantages

Vacuum generators that function according to the Venturi principle are especially suitable for very high accelerations
Vacuum grippers can be controlled individually
Ejectors in different designs for centralized and decentralized vacuum generation depending on the application
Various power classes to suit the workpiece and application
