I partially answered this. The Eaton web page says that the pump
generates 73 dba (at what distance?). This page:
http://www.rfcafe.com/references/gen...ound_level.htm
shows various sound levels. The level for a washing machine is 55 - 75
dba at 3'. Assuming the Eaton measurement is at a similar distance, the
compressor is a bit quieter than a washing machine at its noisiest
(agitate cycle, I suppose). I'd say that's pretty quiet.
