Just an idea.

Seem to be very similar noise wise to screw and vane compressors.
This screw in 2.2kw flavour is listed as 60dB - http://www.fps-compressors.co.uk/fle...mpressors.html
That 2.2KW ABAC screw I mentioned above is listed as 61dB

Although having checked, the hydrovane is the noisiest at 69dB, which is the same as the compressor in the first post.
