Ejectors

Air Ejectors

Air Ejectors are simple devices that operate on the basis of the jet Venturi principle. Typically Air Ejectors have 3 connections

  • 1. Compressed Air Inlet
  • 2. Suction
  • 3. Outlet
Air Ejectors

During operation air ejectors are able to create a pressure differential across its suction and outlet openings. Air Ejectors utilize the energy in compressed air to create this pressure differential.

This enables air ejectors to be used for creating vacuum / low pressure at its suction. The low pressure allows the air ejector to suck air, gases, vapours, fumes, powders, dust, etc through its suction. The pressure of the sucked media increases inside the ejector and eventually it is discharged at a higher pressure from the outlet. The discharge contains the mixture of compressed air & the sucked gases and media.

This phenomenon allows the Air Ejector to be used for large variety of purposes such as compressing air & gases, inducing air & gas flows, vacuum creation, sucking and discharging vapours, fumes, powders, etc

The amount of gases sucked and pressure differential achieved depends upon the size of the Ejector and the internal construction.

Further the operating flows can be controlled by regulating the Compressed Air, Suction & Discharge Pressures.

Air Ejectors

Typical Applications

Benefits of Air Ejectors

  • 1 Static Device without any moving parts – ensure long reliability and maintenance free operation.
  • 2 Use Compressed Air as energy input / fuel – Compressed air is readily available in most setups hence no additional infrastructure needed for operation.
  • 3 Tolerate entry of liquids & solids particles into the ejector – avoids abrupt breakdowns.
  • 4 Small & compact size – allows installation in tight spaces & difficult to access areas.
  • 5 Non sparking operation – can be safely used in hazardous & flammable areas
  • 6 Manufactured in multiple materials – allows using the most cost-effective & chemically compliant materials for the application.
