My wife and I went shopping this weekend at Big Lots and have come across what we consider a 'deal' - an electric air 'pancake' compressor for $88. The specs. are as follows: 3 HP Peak, 4 gallon, 120 volt / 60 Hz. Weighs 57 #s, fits in an 18" square cube of space. 1/4" NPT outlets. 6.78 CFM @ 40 PSI, 5.29 SCFM @ 90 PSI, 115 PSI Max. We aren't running a shop, nor do we have big construction plans. What we were anticipating is having a compressor for quick work, which might spring up. Don't know squat about air tools - thats where you folks (hopefully) come in. What tools can this thing handle? I don't need pneumatic jack hammers - I'm looking at impact wrenches, air hammers (nail gun), that sort of thing. Should I pass on it or run over there and snap one up - there were eight or nine on display, as it was. Thanks in advance for the advice.
