...for my fiancée's father. The guys have been doing all of the body work on my Mustang over the course of a couple of years. He refuses to take money (helluva nice guy), so instead, I've been buying him tools for his garage. I've been buying things like a sand blasting cabinet ($200), a nice 4000 lb jack ($140), etc. The focus isn't on the price of the items, but rather their usefulness vs. what I can afford.

Between what he already had and what I've bought him, he's pretty much good to go for tools and appliances now, with the exception of an air compressor. He has two old, smaller ones (~5-10 gallon, sideways style) that he has linked together for anything that requires a decent flow of air. He gets by with running just one for most things, but for some jobs he needs to fire up both.

To make a long story short, I'd like to get him something newer and nicer that can single-handedly replace both of his old compressors. My budget is around $200-250, and I can do up to $350 absolute max. Unfortunately, I don't know what the CFM, horsepower, or other specs are on the existing ones.

Any suggestions for something in that price range that should handle whatever you throw at it, or do you really need to go into the $400+, 2.0+ HP, and 40+ gallon models to get something powerful enough?

Thanks. :)

I assume if he is doing body work he is using air tools. You already said he is using a blasting cabinet which uses tons of air. At your price range you can't afford to pay for a compressor to keep up with a blasting cabinet (can be above 30 CFM). But, you probably can get a name brand compressor, prob 20 gal tank, and CFM in the 10-13 CFM range. There are other things to consider - does PSI matter? Access to a 220v outlet?

Yeah lots to consider.

Also, get a water separator if he doesn't have one - that's always a good thing to have when using a lot of air tools - also the cheaper compressors will be worse with having more water get into the line.

You will probably not like what I am going to recommend. If I were to buy an air compressor for an automotive body shop, I would get about an 80 gallon tank, upright model with at least a 5hp 220 volt motor, and can put out 175psi with a relatively high cfm. If he uses air tools a lot, and does sand blasting, he will need the higher pressure, the higher volume and the higher cfm.

Couldn't agree with you more.

What you are sugggesting costs about 2k+ new. See the CL thread....I have one of these in my garage that I picked up for a cool $340.

The dad sounds like a guy who has made it work with what he has, therefore something smaller is much more doable and affordable.
Would you consider trolling CL and getting him a used one? Took me 4-5 months to find my deal.

And my solution for water separation was running about 60 feet of 3/4 in black steel pipe, using drop-downs and water separator/regulator/oiler from Northern Tool.

He's been making do with what he has, and anything at this point would be an upgrade. Apparently one of the old compressors is acting up.

I'd like to get him something substantially better than what he has now, though I simply can't afford something in the $500+ range, let alone $2000+. I would LOVE to get something like what JimW recommended, but it's simply out of the question.

The bottom line is, if he's been doing everything he does now with what he has, SOME kind of upgrade can't be a detriment. If it still won't run everything he has off a single compressor, so be it. I'd love to just hand him the cash so that he can save it for something better, but unfortunately (for me, from a moral standpoint) he'll just put it back into the car, or find some other way to return it. Like I said, he's a helluva guy. I wish I could save up for another several months and buy something better as well, but I haven't bought him a gift in a while, and it's really about time to.

Things I recommend if you are simply looking to have him upgrade.

Oiled compressor
At the price range you're looking at, you can probably get an oiled compressor with around 4-5 CFM @ 90psi.
Capacity around 25-30 gallons

If you look used you can probably get about twice the above specs for a similar price.
