OK verdict in. Noise is not louder than VPI vacum.
I'm not sure you are catching my point. Of course the audible noise is not excessive, but the ultra sonic cleaners are putting out high volumes of noise that you
can't hear. More importantly, it's in excess of 100 db's in the near vicinity of the cleaner. Just because you can't see U.V or Xray frequencies doesn't mean it can't damage you. Please advise your customers to use hearing protection when using any ultra sonic cleaners.
And a 20% discount, made a good deal into a great one....
