i have this northern tool compressor, bought with the kit for the extra warrantee. it's a workhorse. notice it's a continuous duty compressor. i use it for sandblasting for hours at a time. check it before it comes off the truck though, as the first one i got had a smashed up regulator. the 2nd one was good though.

Thanks - that's what I figured but it had the benefit of new condition and close proximity to make moving easier. Not seeing it run was a real deal killer, now that the excitement of the find is past. Delivery of new stuff by truck is always a problem here unless I want to waste a day off work waiting for the trucker to show up and probably another when they have to come back with the lift gate that was requested. That makes local pickup attractive, but not for used tools of unknown condition at retail prices.

Iggy - I've been watching CL for a few months now and that's where this one showed up. Most of the ones I've seen there are horizontal, beat to heck or of unknown quality. I also check Ebay frequently in a 100-mile radius with pretty much the same results. CL has the advantage that it is usually easier to arrange an inspection in person but has the disadvantage that the good deals go quick.
That Speedaire at $52.50 looked like a bargain, but it's around 4 hours from me making it a bit of a pig in a poke since a pre-bid inspection is hard to do.
Keep me in mind if you pick up a nice vertical compressor in your scrounging that you want to unload.

OK. I also have a nice compressed air dryer.
iForgot to add Mike, but I would also suggest looking for a "real 5 HP" compressor. It would improve your productivity working on certain tasks such as sanders or air hammers, on real projects.

The 3HP IR he's looking at produces more air (11.3 acfm @ 90PSIG) than some "real 5HP" units do. Exceptions would be 2-stage units. Buying a used compressor (except perhaps a Quincy) is a bit of a crapshoot unless there is some way to know its history.
My 5 HP compressor makes about 14 CFM. It is single stage.
Your point on used compressors is quite right.

That's nice. Where can Mr. Henry buy one like it next week, pray tell?
5 HP (with 15% friction) can theoretically deliver 25.6 ACFM at 90 PSIG in adiabatic single-stage compression. Pumps vary a lot in efficiency. More efficient pumps tend to be larger and more expensive. Example: IR pump model S-20 (single stage) delivers 19.5 ACFM @ 120 PSI with 5 HP. Figure about $1300 just for the 155-lb pump.There are also "consumer models" that deliver less than 10 ACFM from 6 HP.
My point was to look at ACFM, not horsepower.

I always heard that it's better to rent than own.
