NOISE CONTROL ejectors
STEAM BLOWING noise reduction
STEAM BLOWING noise reduction ejectors have no mechanical moving parts and are powered by high‑pressure steam tanks.
The ejector reshapes the free steam jet, modifying the flow pattern so that the resulting noise is significantly lower.
The device does not absorb noise — it changes the way the jet flows, producing a quieter output.
This technology was first designed and tested by Henri Coandă and has operated for more than 20 years without maintenance.

Usual ejector types for this application are:
FORMULA ONE exhaust systems
FORMULA ONE exhaust ejectors have no mechanical moving parts and are powered directly by engine exhaust gases.
The ejector reshapes the gas jet, producing a quieter flow pattern and reducing emitted noise.
Tests showed that engine useful power increased when ejector systems were installed.
