Gas Ejector
Gas are simple devices that operate on the basis of the jet Venturi principle.
Typically Gas Ejectors have 3 connections
- 1. Gas Inlet
- 2. Suction
- 3. Outlet
During operation Gas Ejectors are able to create a pressure differential across its suction and outlet openings. Gas Ejectors utilize the energy in process gases to create this pressure differential.
This enables Gas Ejectors to be used for creating vacuum / low pressure at its suction. The low pressure allows the Gas Sampling 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 process gas & the sucked gases and media.
This phenomenon allows the Gas 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 Process Gas, Suction & Discharge Pressures.

Benefits Of Gas Ejector
- Static Device without any moving parts – ensure long reliability and maintenance free operation.
- Use Process Gases as energy input / fuel – Process Gases are readily available in most Oil & Gas Industries & refineries hence no additional infrastructure needed for operation.
- Tolerate entry of liquids & solids particles into the ejector – avoids abrupt breakdowns.
- Non sparking operation – can be safely used in hazardous & flammable areas
- Non sparking operation – can be safely used in hazardous & flammable areas
- Manufactured in multiple materials – allows using the most cost-effective & chemically compliant materials for the application.
