I'm a complete noob when it comes to air compressors and I was seeing if any experts on here can help.

I'm looking into purchasing a compressor for just basic tasks, changing tires, filling up air in tires etc... I came across two compressors and can't figure out why the one with a smaller capacity would be more expensive than a bigger one.

20 gallon (http://www.canadiantire.ca/en/pdp/20-gallon-oil-free-compressor-with-3-peak-hp-1995704p.html#.VglrJt9VhBc)

11 gallon (http://www.canadiantire.ca/en/pdp/mastercraft-11-gallon-air-compressor-0588386p.html#.Vglqzt9VhBc)

To me they seem to have the same details, just one has a bigger tank capacity. Also, would these be more than what I need for my tasks?

If anyone can chime in with some knowledge it would be greatly appreciated.

Oil-less compressors are not really built for the long term. They are noisy, and when they break they are disposable. I'd second Sugarphreak; I only break out my compressor when I have something that needs it (leak down tests, blowing out passages). Otherwise I use my 1/2" cordless impact (which I use often) and 12V compressor.

BTW, I got my oil-less 17 gallon compressor for $85. Looking back, it wasn't a good deal.

If you are dead-set on getting a compressor, get an oil-type that puts out >4 cfm@90 psi (120V) or something like this: https://www.kmstools.com/california-air-twin-stack-compressor-93436. If you are serious, get a 240V compressor that puts out >10 CFM @ 90 psi

For general homeowner stuff with occasional car work, I'd look at something like this:

http://www.canadiantire.ca/en/pdp/mastercraft-8g-compressor-1991588p.html#.Vgl1epfGpJM


It's not got a huge tank, it's not super powerful, but it's got an oiled compressor and it's cheap. I bought basically the same unit years ago, assuming I'd eventually upgrade to a bigger 240V one. I never bothered, it runs my impact and air wrenches just fine even if it does run more frequently than one with a big tank. I'll probably only upgrade if I get a blasting cabinet.

For running an impact reasonably,no little compressor does that.

as said, stick to an electric impact, or get a bigger compressor. I have the 60 gallon sanborn from princess auto. I got it on sale for under 600 i think if i remember. Its done me well for 2 years so far.

Too many people think too hard about the diaphragm vs piston/oil vs oilless compressor.

I've had the same diaphragm compressor for a decade. It still works fine :dunno:

For your uses, practically any compressor will work. It starts to become more important when you start using air powered tools (at least 5scfm @ 90psi is a typical requirement).

As for the pricing difference, Canadian Tire does this all the time with plenty of their products. The pricing doesn't have to make sense, they just have to convince you to buy it!

I would assume my little impact driver has enough torque for this? Where would I find adapters for lug nuts?

That's an impact driver. Great for driving in deck or fence screws. You can buy an adapter for it, but they tend to hammer rather than twist. Not really up to the task for lug nuts, but can work with 1/4 and 3/8's stuff (depending on the torque output).

Something like this is what you want for lug nuts:

I have some shitty electric impact driver from crappy tire. I always break the lug nuts when the car is on the ground using a breaker bar, and a do final torque with a torque wrench, so i don't think torque output of the electric tool is really that big of a deal.

Yea I wouldn't mind if I need to break it before using my little driver... still need to figure out how to get approriate adapters then...

I got in the habit of breaking them first on the ground after I saw a vehicle fall off the jack when being yanked on. Not really the same safety issue with an impact wrench, but I still do it that way.

^lots of places like Home Depot, princess auto or even crappy tire have those as well. Dewalt are very good ones that last a long while. We've had our Dewalt ones for probably 10 years now, they've outlasted numerous drills, still work perfectly fine.

I don't think I'll do enough work in this lifetime to break a crappy tire one. Maybe I'll cheap out :D

I have an air compressor at home, the only thing I use it for now is my air riveter and blowing out the sprinklers in the fall, I use my dewalt cordless imact driver for everything, if its a larger bolt, crack it by hand and zap it off with the dewalt. I can't stand the noise an air compressor makes.

These products 1995704 and 0588386 both have the same motor. This item# 1995704 is cheaper because it is a limited time promotion with limited quantities available! We may not be able to issue rainchecks for this special promotion.

So yes, they are identical except for the tank size.

As others have stated, give some serious thought to what you want a compressor to do before you invest the time, money, and space in one. Many times, hand tools are more than adequate, and for those occasional larger jobs (framing, shingling, laying hardwood floor, etc), rent a compressor at the same time you rent specialty tools and you'll be money ahead.

I have an air compressor and air tools but they've pretty much been replaced by my Milwaukee Fuel impact. The one I have has 700 ft-lb of torque. Having no cord or hose hanging behind you is awesome.

I've been curious about those. I wonder if the Bosch is any good? I've got a couple Bosch tools and battery packs already and it's nice to keep things interchangeable.

SPOTTED: my next purchase. Holy shit it looks awesome. I just wish there were more modes then either 100ft pounds or 700. Oh well, most shit falls under the 100 catagory. So works for me. :)
