Choosing my air compressor

Seems compressor threads are popular recently, but I'll beg everyone's patience as I'd like to discuss a compressor to meet my needs. I've recently purchased a house that now gives me a garage of my own to work in, rather than having use of my Dad's. My application is basically as follows:

- evening and weekend user. For the most part if I'm working on something and run out of air, I can wait for the compressor to catch up, I'm not in a rush.

- probably 65% of the use is just inflating tires, and running low-intensity air tools like a brad nailer.

- maybe 25% of the time would be an impact wrench, air ratchet, and tools that put moderate and intermittent demands on the compressor.

- the last 10% would be die grinder, or an HVLP paint gun for modest size projects (say painting furniture and such) that requires more air capacity.

My father has an older Craftsman compressor, about 2hp and 25gal or so. It's been good for this sort of application - at times I've wished for a tad more air, but never been seriously short. Based on all that I'd say my *needs* are actually for a compressor of about 8-9cfm with about 30gal tank. And I don't want to go too crazy with a huge tank given the intermittent sort of use I'll have.

Dad's initial thought was that I should buy a small twin stack compressors, and an extra reservoir tank, and if needed I can borrow his compressor. His thinking is that I could do it a bit cheaper for now, and use the money elsewhere. That said, a little compressor would be outgrown quickly, and would cost $300-400 by the time an extra tank was added to allow me to use an impact intermittently.

My budget isn't fixed, but with house and shop projects competing for funding I don't want to overspend. I also don't want to buy something that won't meet my needs for years to come. I don't think twin-stage is necessary, or within what I'd want to spend, but I should be able to get a decent oil lubricated single stage. I'd actually prefer a horizontal, but most of what I've found is vertical. I do have 230V wired already. So here's what I've found, and my comments. Any other suggestions, recommendations, or comments (especially on the I-R and Quincy - are they good, and are they good value?).

PPA1982054_500.jpg

Powermate IPA1882054
120V - 1.9hp - 20gal - 7cfm@40psi, 5.7cfm@90psi - oil lubed, belt drive
Specs are comparable to Dad's. Probably very close to what I need, Portable could be useful, although not necessary. About $500, and easily available.

SS3L3_500.jpg

I-R SS3L3
230V - 3hp - 60gal - 11.3cfm@90psi - oil lubed
Continuous duty is good. Doesn't include the regulator or startup kit. But for not a lot more money it looks like it's twice the compressor. About $800 either from a dealer locally, or from a cheaper retailer that would require some driving.

Quincy Q13160V
230V - 3.5hp - 60gal - 12cfm@100psi, 14.6cfm@40psi
Looks nice, probably close to $800 to get it home, maybe a bit more to buy from a local industrial supplier. Don't know anything about Quincy - good stuff? Does this go on sale at Northern Tool ever? Do they stock it? Is the 26gal Quincy worth looking for?

VT6271_400.jpg

C-H VT6271
120/240V - 26gal - 3.2hp - 10.3cfm@90psi, 11.8cfm@40psi
It's horizontal tank, big pump, and a moderate sized tank - almost perfect for what I'd need. However C-H doesn't seem to be as favoured by most people. And I don't care for the plastic tires. Also, it doesn't seem to be in stores locally so probably won't get a great deal on it. But for those 2/3 of the time when only a single fill of the tank gives enough air to use, having a moderate sized tank would be more energy efficient.

Other - perhaps Craftsman, Husky or C-H 60gal. 3hp models? I've also seen reconditioned Morgan and C-H 60gal units that looked like good deals ($300-400), but are they too good of a deal to be true???

It's really all personal preference on how many gallon compressor you want. I can say this from many years of using air tools. you can never have enough air storage. Right now I have a 5hp 80 gallon 2 stage compressor and run it hard when using my sandblast cabinet, die grinders and spray guns. I still have my old devbliss (sp) which is basically the Quincy you have shown. It lasted through 7 years of hard usage before the pump blew. It wound up being cheaper to just get another compressor then replacing the pump. That old comp will soon be piggy backed so I have 160 gal of air on reserve.
I have done some painting with a small roll around compressor, but the thing never shut off and had a hard time keeping up. What I would do is check to see what the cfm rating is for the tools you plan on using. Use the rating for the one that uses the most as your base line.

I think any of those will work for you for a while. The only one that's likely to make you want more air is the Powermate. If you don't really need a portable, I'd skip that one.

Northern stocks the Quincy online. Not sure about in-store since we don't have their stores around here. They also have the SS3L3 delivered to your door for $620. Both of these units are good values. A couple of people also just vouched for the PUMA in another thread. I think if you aim for 10+ cfm @ 90 PSI and a 60-gallon tank, and maintain it well, you'll be happy for many years to come. Below that and there will likely be times when you wish you had more air or at least wish the compressor wasn't running so much. As soon as you add a sander, or need to use the die grinder for a longer job, you'll likely want more air than the Powermate will deliver. Speaking for myself, nothing kills my sanding or grinding mojo more than having to wait for air many many times on a long job.

I like having items this size delivered. It usually saves me a lot of time and also relieves me of delivery damage liability (and potential injuries from my endless supply of foolishness :)).

I like vertical. My SS3L3 is on a rolling platform so I can still move it around with relative ease when needed (mostly so I can clean up behind it).

If you're considering $800+ for a single stage compressor, you should consider an economical 2 stage unit. If that's not your cup o tea, buy two CH units and tie them together. You'll have more air for the price of one cheap IR or Quincy.

I, too, like vertical, but if I went horizontal I could save a little shop space by mounting it up on a shelf / mezzanine type idea. I'm also figuring on plumbing lines around the shop, so portability isn't an issue.

If you're considering $800+ for a single stage compressor, you should consider an economical 2 stage unit.

$800 is sort of the outer limit of where I'm thinking... more along the lines of hoping to get something like that on sale, or go for something a tad cheaper. 2-stage looks like it's all in the $1200+ category.


I'm in Canada... so I can make a run across the border to pick stuff up from the store, but shipping something so large is cost prohibitive. And I'm going to try to stay with local options, but it will depend on availability and not paying too much of a premium in price for whatever I end up choosing. Really wish I could get it delivered economically, though.


Anyone have comments on the advisability of going with remanufactured?

What would be an economical 2 stage 80 gallon unit that would last a long time?

Depending on the price and if you don't mind running 240V I would buy the CH mentioned above for doing what you do. I have a 25 gal horizontal and love it, although I like it because it's similar to the powermate and you can take it around back or wherever and plug it in to a 120v socket.

I wanted a 120v unit so I bought the 25 gallon Craftsman Pro, but if I had 240V that CH would be my sweet spot IMO. No real reason for a 60 gallon tank if you are inflating tires, why spend the $$ on filling a 60 gallon tank? Only 10% of your time will be spent doing stuff like die grinding and even my 5.7 CFM 25 gallon can handle limited quantities of that.

Also FYI it appears to be a solely 240V unit, not 120/240 like you've indicated.
