Vacuum Venturi Generators and Ejectors

Venturi Generators

Compact Vacuum Generation from Compressed Air

Venturi vacuum generators, also known as vacuum ejectors, use compressed air to create vacuum without a mechanical vacuum pump. Their compact design makes them well suited to decentralized pick-and-place systems, robotic end-of-arm tooling and automated material handling.

Because the internal air passages can be small, a vacuum inlet filter is recommended to help prevent debris from the application entering the generator. Correct sizing of the generator, vacuum cup, tubing and compressed air supply helps improve response time and overall system efficiency.

Venturi Generator Features

Virtually maintenance-free vacuum generation
Single-stage, dual-stage and three-stage technologies
Multi-function generator models available
Energy-saving kits available
Compact installation close to the vacuum point

Why Use a Venturi Vacuum Generator?

Venturi generators can create vacuum directly at the point of use, reducing the length of vacuum lines and helping automated systems respond quickly.
They are especially useful on repetitive handling machinery where vacuum is needed only during part pickup and transfer.

Common Applications

Robotic pick-and-place systems
Packaging machinery
Carton and sheet handling
Automated assembly equipment
Machine loading and unloading
Vacuum grippers and end-of-arm tooling
General factory automation

Frequently Asked Questions

How does a Venturi vacuum generator work?

Compressed air passes through an internal nozzle arrangement that creates a low-pressure region and generates vacuum at the suction port.

Is a Venturi generator the same as a vacuum ejector?

Yes. Vacuum generator, Venturi generator and vacuum ejector are commonly used terms for this compressed-air-driven technology.

What are Venturi generators used for?

They are commonly used with vacuum cups in pick-and-place, packaging, robotic and material-handling applications.

Do Venturi generators need an inlet filter?

A vacuum inlet filter is recommended to help prevent debris from entering and obstructing the small internal passages.

Do Venturi generators have moving parts?

Venturi vacuum generation does not rely on a rotating mechanical vacuum pump, which contributes to low maintenance requirements.

What is the difference between single-stage and multi-stage generators?

The source range includes single-, dual- and three-stage technologies. Selection depends on the required vacuum level, flow, air consumption and application response.

Can Venturi vacuum systems save energy?

The source product range includes energy-saving kits. The most effective setup depends on how often vacuum is required and how the machine cycle is controlled.

How do I size a vacuum generator?

Consider the cup size, number of cups, leakage, required evacuation time, tubing volume, vacuum level and available compressed air supply.
