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.
