D systems

Working domains

Sucction pressure 100 to 90000 Pa
Sucction flow any kg/s
Supply pressure any barg
Kinetic efficiency 13-70 %

Sucction pressure[Pa] vs Sucction 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 adjustements or each flow conditions and each customers needs.
The Coanda ejector is more complex flow device than a simple rotor fan or blower therefore the flow characteristics is done by adjustments of geometric dimension, pressure and temperature. The input temperature is critical for the efficiency of the device.
The diagrams sucction pressure [relative Pa] vs sucction flow [kg/s] for different "p" supply pressures [barg] might have any possible working point.

Geometric configurations

Coanda ejectors S systems is design as a group of A x B x C ejectors of same type, coupled to work togheter.
The Coanda ejectors S systems might be design in any working configuration that is fixed in a specific place or shape following the customers specification:

The Dsystem 4x4 or simmilar is used for rectangular, squared or circular ducts, pipeline, channels, mines gallery, tubes or other cases when have to move large and very large flows of air or other fluids including steam and water.

The Dsystem 2x7 or simmilar 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 2x2x2 or simmilar is used to create high pressure for large flows. The systems is designed to move with high speed of large and very large flows of air or other fluids including steam and water.

Lenght flat design mm
Duct any mm
Weight A x B x C x HD type kg
