HD150 ejectors

Working domains

Sucction pressure up to 25000 Pa
Sucction flow up to 2 kg/s
Supply pressure 3 to 7 barg
Kinetic efficiency 13-70 %

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

The HD150 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 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 therefore the efficiency is not shown on the digram because is depending on the input local customer conditions.
We present only five representative diagrams sucction pressure [relative Pa] vs sucction flow [kg/s] for different "p" supply pressures [barg] as follows:

HD150_500

HD150_400

HD150_300

HD150_200

HD150_100

The diagrams were estimated using Coanda ejectors compressible invicid flow theory based on AERODIN know-how and there are not fix but closer to the experiments.
