Everything is awesome with this compressor. I have to say it is literally the quietest compressor I have ever stood next to. Even when it's ramped to 100% it's half the noise (less even?) of any rotary screw I've experienced. (Atlas, Sullair, Kaeser, etc)
Had to wait until Atlas Copco sent out a rep to do the startup last week, but when they do it it bumps the warranty to 5 years.
I would also recommend Fastpipe. Super easy to install and just as easy to remove and re-use. I put up a 40' x 60' loop at the ceiling 18' up by myself, with 4 drops (including 2 hoses to the presses) and the hardest part was driving the lift around the existing equipment. The fittings are pricey but pay for themselves in labor over a traditional pipe fitter.
