The compressor finally arrived this afternoon. I installed the feet and mufflers and plugged it into my lathe 220vac outlet for a quick test just now. 81 decibels standing right in front of the unit, 75 decibels about 20 feet away as advertised. I think they advertise the decibel rating at 9 meters away. The noise is not harsh, I'm not sure I would say it was soothing but almost. Sounds a bit like a back massager I don't think it will annoy me running. A very nice noise reduction from the 95 decibel Rolair.
So now I need to find a permanent home for it and run some power. Edit: Interesting, I see the tank looks like its flat white paint its actually high gloss.
