Vacuum Generators Pneumax

Vacuum generators have one and only purpose… to create vacuum. Vacuum generation
has applications in industries that require heavy object handling.
Vacuum generators can be either pneumatic or electric. Pneumatic generators
use the pressure of compressed air to create a vacuum while electric ones
generators use a displacement pump. Electric vacuum generators are also called
vacuum pumps.
In addition, pneumatic vacuum generators are often combined with vacuum suction cups. The suction cup is connected to the output of the generator and then connected to the object that the operator wishes to transport

Pneumatic vacuum generators they can be integrated directly into the system thanks to the lightweight
and their compact design. Depending on the number of pairs of nozzles, they are divided into
single-stage, multi-stage vacuum generators and jets. Vacuum generator operates
based on the Venturi effect.
Single stage

It consists of a jet nozzle or Venturi nozzle through which the
the compressed air Because of the very small diameter of the hole from the nozzle
it causes the air to accelerate. As it passes through the narrow nozzle and begins to
expands, a gap is created on the expanded side. Air is drawn in through the
inlet and the compressed air exits through the muffler.

Multi -stage

A multistage vacuum generator has multiple Venturi nozzles lined up in a
row. The compressed air passes through a connection port. After that through a
row of nozzles. As the vacuum is created, air is drawn in from the inlet. The
suction rate from the inlet is the sum of the suction from the individual
generator nozzle. A multi-stage generator can offer a higher
suction rate for the same supply of compressed air

Advantages of a Vacuum Generator

• Their small size and lightweight body makes them ideal to be installed near the application
  spot
• Rapid vacuum creation
• There are no moving parts, so little to no wear and tear and therefore no cost
  of maintance
• They dont produce heat
• Low purchase cost, but need compressed air supply wherever they are,
  condition that can increase the amount of the investment.
