NOISE CONTROL ejectors
STEAM BLOWING noise reduction
The ejectors works as STEAM BLOWING noise reduction are no
mechanical moving parts devices powered by a high pressure
steam tank. The ejectors device is changing the flow of a free
steam jet in order to reduce the noise. In fact is not
reducing the noise but by changing the way to flow it produce
lower noise. The final effect is to reduce the noise emission
but is not about a reduction of an initial noise. The product
was first designed and tested by Henri Coanda, working more
than 20 years without any maintenance. (photo FourQuest

Usual ejector types for this application are:
FORMULA ONE echappements
The ejectors works for FORMULA ONE echappements (exhaust
systems) are no mechanical moving parts devices powered by
engine exhaust gases. The ejectors device is changing the flow
of a free gases jet in order to reduce the noise. In fact is
not reducing the noise but by changing the way to flow it
produce lower noise. The final effect is to reduce the noise
emission. The product was first design and test by Henri
Coanda. It was observed that useful power of the engine was
increased by the presence of the ejector systems. (photo
