That'* about the same size as what I got.

I have a 3/4" drive impact gun too

I probably need a bigger tank for extended use, but the big impact is only for things like FWD driveshaft/etc... bzzzzt and it'* off, as opposed to the 1/2" drive which will barely get it off if at all.

I'm going to look around for some used ones in the paper.

thats what I need minimum to run a 1/2inch impact wrench right.

I need about 7+ at 90PSI to run most 1/2 inch impact wrenches.

Right..which turns out to be more like..you want about 20 gallons or more at 125psi with a compressor that has a quick recovery rate.

I laughed a bit when I saw Stan'* compressor picture. Reason is..many of those large standup compressors had turtle recovery rates and made up for it in the tank size and price. If you do your homework and buy the right large upright compressor, you can supply the world with air...like a dealership. (Which..knowing that nut...he'* got the good one)

You'll want to go with the bigger 7 gallon. It will do what you want it too. I have the smaller 3 gallon and you can take off about 5 bolts before it won't keep up anymore.

Nice thread hans. I am looking as well for a compressor. I like the idea of having it out back in an enclosure.

i scooped up my 15 gallon craftsman for $100 at the pawn shop... works like a charm

Get at least a 15gal one, have a 13gal one right now, and when i use the Air Hammer or Air Ratchet it makes that thing empty out quick. the Impact gun works well, but i still wish i had a 20gal one

I have a 1.5hp that produces 3.5cfm @ 90psi, 5cfm @ 40, 15-gallon tank, and goes to 150 psi. It keeps up with heavy die-grinding and engine disassembly with an impact gun and an air ratchet being used alternately.

My compressor is considered to be about the bare minumum for heavy sanding and painting as well. You don't want to go any smaller. I chose this one simply because it was as large as I could go and still consider it somewhat portable.

Agreed with what everyone has said here. Our compressor is like a 3 (maybe 5) gallon at 130 PSI. I have a "Mini" Die grinder and it will run it down to where it has to run again in less than 30 seconds.....annoying as hell.

I will admit it is really super nice for portability though. We got this one for doing wood floors in our house, super nice to be able to move it around so much.
