How Coanda ejector works

Coanda ejector is a geometric device, having no moving parts, that create an induced flow using an input fluid flow coming from high velocity fluid power.
The common working fluids are air and steam.
The Coanda ejector (yellow) is coupled to an existing diameter flow duct.
As soon as the ejector is powered on, a vaccum is created (red zone) and an induced flow suddenly appear.

Special Coanda ejector particularities

Coanda ejectors have 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 for 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 therefore the efficiency is depending on the input local customer conditions.
