More Information about Vacuum Generators
Vacuum generators (sometimes called vacuum pumps) are simple devices with no moving parts that use compressed air to create a vacuum.
Compressed air is supplied to the inlet of the vacuum generator where it is directed through a venturi. As the air leaves the venturi and expands it creates a vacuum. Vacuum generators are available with multiple venturies to optimize vacuum generation.
Since compressed air is available in abundance throughout most manufacturing plants, vacuum generators are ideal for applications that require a minimal amount of vacuum. Many machines use venturi style vacuum generators to provide power to their vacuum cups. The vacuum generators are often installed at the location that the vacuum is needed, sometimes with the vacuum cup attached directly to the pump.
Most vacuum generator manufacturers offer a modular system to ease installation. The modular accessories include compressed air supply control valves, compressed air blow-off control valves, vacuum switches and vacuum gages. Multiple generators can be mounted on a single supply manifold.
Vacuum generators can be used in hazardous locations. Since there are no moving parts and no electrical signals, the vacuum generator is ideal for explosion-proof applications.
