Default Large home air compressors

I have been looking for a good sized air compressor for the house for a while adn many of the smaller portable ones are nice with 20gal+ tanks but the CFMs are always too low to run air grinders, ratchets, even some larger impact wrenches for lug nuts/engine mounts etc plus having a sandblasting booth.

I have come across 2 that are almost identical to each other as well as one sold at sears.
THis is the Camp Hous model, and sears sells it for $700, lowes has it for for under $400 at times on sale, like $375~
http://www.lowes.com/pd_102750-1126-...eld_4294813361 4294962947_4294937087_

Home Depot has this one, first I have seen of the (reconditioned) label, never saw that before now
http://www.homedepot.com/Tools-Hardw...atalogId=10053

These are the identical sears models,

Thanks

I have the Home Depot one in my garage (new, not recon) and love it; had it about 1.5 years now. The first one you listed is 230 volt which may be an issue for you, maybe not. I would not buy an oil-less, which the three you listed luckily are not. The home depot one makes plenty of air, but the motor will not run right if you plug it in with too small of an extension cord. Because it is 120 volt, it needs all 15 amps to run properly.

Can't say anything positive or negative about the others because I haven't used them, but they may just as well be good machines.

Do NOT buy an oilless compressor! The larger the tank, the better...gives much more reserve. I'd rather have an 80 gallon tank with a small compressor than a 20 gallon tank and big compressor!

I have the depot one, four years old. Works great, just plumb it with 3/4" pipe and large filters/separators. Large impact guns need large dia. supply hose and will empty the tank quick. For the garage it's great. You have to hard wire this thing 220V, no
extension cords. This is the only large reasonably price AC I could find, the next step up is well into the +$1000.00 range IR and speedaire 2 stage AC's.

I have the exact model in the Home Depot photo and use it for Sandblasting and grinding. Hardwiring is easy.....or, use a plug that goes into your dryer unit. Sounds like you may not require a heavier duty unit. Great Value for this low priced unit.

I've had a porter cable "semi"-portable 20 gallon 7.something SCFM for eight years. It is great for light-medium tools, and other shop jobs, but I wish I had gotten one with more output. Big Impact tools and pneumatic jacks really tax it and you have to wait for it to catch up. If I had it to do over, I would buy one with considerably more output.

As the previous posters have mentioned, don't go oil less. Also, bear in mind that for the larger compressors, you need sufficient amperage.

I highly recommend installing a spring retractible hose reel. Battling air hose can be a pain, but with the reel, one tug and the stuff is neatly coiled. It is not a big deal when you are fixing to rotate tires or service farm equipment, but it is sure handy when you just want to top off the pressure in a tire.

Keep in mind if you plan to do sandblasting or spray painting, you need either an oil-less or one of those several hundred dollar filter systems.
Oil lubed will last longer if used often; on the other hand I've got a 30 gallon oil-less for more than 15 years with no issues.
Keep in mind the requirement to regularly dain the tank - water will corrode it.
As for tank size, anyting in the 20-60 gallon range will run anything one person using a single 3/8" hose could ever buy. Body shops, which can have 6-8 people using them will buy 2 stage 175 psi, 120 gallon units - but a set up like that will run you $2,500.
I beleive all three you have links for are the same chinese 60 gallon units, so buy whichever color suits your fancy.

I'm no expert, but when I buy my next one it will be an IR 5 hp 2 stage. I think 80 gal will be enough and should be under 1k.

Purchased a IR 14.1 SCFM @90psi 5Hp 60 Gal from northern a year ago. Works great and wish I had it a few years ago. 230V if wiring is a problem and they offer free delivery. One thing If I would have known better I would have purchased a two stage for a few hundred more.

And I'll either be just in front or behind you in line.

I can't wait for that loud POS verticle tanked oil less compressor to die. I don't drain the tank, clean the filter, or ever shut off the switch in case the air hose splits. What a mistake that purchace was from Sears.

What's the deal with oil-less compressors? Noise, longevity, efficiency?

I have a 1979 Saylor-Beall 5 h.p. 2 stage on an 80 gallon tank that I bought 25 years ago for my paint and body shop it has been trouble free all these years and I think I paid 500. for it used. Quality is hard to beat.

I bought a Husky 1.8HP 155PSI 26 Gal tank compressor from Home Depot complete with a 1/2 inch impact wrench, 3/8 ratchet and various other stuff I'll never use for 199.00 a few years ago.
It doesn't get daily use, maybe 3X a week. I keep the boat on the trailer in the driveway and pull the wheels off with the impact wrench after every use.
It's paid for itself quite a few times already.

I have a craftsman "5.5" hp (menaing less figure - its like 15 or so amps) 40 gal and 6-8 cfm. For 15 years no problems does all I want it to - not great for with a real high air user like the angle grinder when used as cutting. But its 120 -

Bought this beast off craigslist on Christmas eve a few years back. The guy dropped his price to the first person with $300; said he needed to finish his shopping!

Six years old, two stage, 5 hp 220v 80 gallon tank. 175 psi and about 14 cfm. Mounted with 3/4 red heads and sitting on hockey pucks...damn hard to find here in Fla....

Very loud, past irritating. Can't even think when its running. Slow to fill compared to a 2 stage. Runs very hot.

If you work in your shop on a regular basis with air tools they are not for you. If you're a homeowner with a lite need for air then OK.

You could run two pancake compressors at the same time and not equal the noise level of this. It drives me nuts when I want to use my plasma cutter or impact wrench.

Like I said I have zero respect for mine.

I have an oil-less that I bought used and it's like standing next to a machine gun when it runs. It's rarely used, but when I do use it, my wife goes shopping or walking because it's so loud.

Now I know that it's a function of oil-less compressors; not just the one that I bought (cheap).

Thanks for the education.

Well there's no bullshit in that response! ~
Mine, I've just about sold it a couple of times, but it's that damn noise that is the deal breaker. I don't know how many times I've openly expressed, I hope someone would steal the damn thing. At my last place I bought the "best" muffs I could buy and yet when the compressor kicked in I left the garage. At this place, I put the compressor in an adjacent building so I wouldn't have to listen to the damn thing ~ ....it's that loud. But for painting and sandblasting I do like the clean air it produces.

Without a question of doubt, my next compressor will be a 2 stage w/ at least a 80 gallon tank, preferably a 120 gal tank. I would most definitely be looking at the industrial used market for such a unit....I see them All the time.

All the units listed are single stage with outputs less than 10 cfm. They'll be fine for pumping tires, spray painting, and running impact tools. When it comes to sandblasting, or using rotary tools such as sanders and grinders, single stage machines fall far short of the mark. Don't be sucked in by the lure of an 80 gallon tank, as it's won't make up for a compressor head that can't keep up. Although, a larger storage tank lets you run a tool a little longer, it also takes longer to pump back up to usable pressure, so payback's a bitch. I would reccommend a two stage unit with a minimum of 10 cfm @ 90 psi. My son bought a 2 stage about a year ago and it runs circles around my 5 hp single stage upright with 80 gal tank.
