Suction pressure [Pa] vs Suction flow [kg/s]

Any Coanda ejector has 2 main dimensions and also 3 geometric dimensions and 2 other thermodynamic supply parameters (pressure and temperature) in order to control the flow and make the necessary adjustments for each flow condition and each customer's needs.

The Coanda ejector is more complex than a simple rotor fan or blower; therefore, the flow characteristics are determined by adjustments of geometric dimensions, pressure and temperature. The input temperature is critical for the efficiency of the device.

The diagrams suction pressure [relative Pa] vs suction flow [kg/s] for different "p" supply pressures [barg] might have any possible working point.

Geometric configurations

Coanda ejectors S systems are designed as a group of A × B × C ejectors of the same type, coupled to work together.
The Coanda ejectors S systems may be designed in any working configuration, fixed in a specific place or shape, following customer specifications:

The Dsystem 4×4 or similar is used for rectangular, squared or circular ducts, pipelines, channels, mine galleries, tubes or other cases requiring movement of large or very large flows of air or other fluids including steam and water.

The Dsystem 2×7 or similar is used to create fluid flow barriers. The system is designed to move large and very large flows of air or other fluids including steam and water.

The Dsystem 2×2×2 or similar is used to create high pressure for large flows. The system is designed to move large and very large flows of air or other fluids including steam and water at high speed.
