I haven't begun shopping for this, but I'd like to have a small compressor
in my garage for topping off tire pressure, and for times when I need to
blast dirt/dust out of engine & boat crevices. I'd prefer something that
doesn't take up as much floor space as a gas grill, and it should be AC
powered, not one of those portable that you keep in the trunk of the car.
Anyone have purchasing/feature advice, and perhaps some brands to look for,
I fell heir to a Sears 1HP unit several years ago and can't do without
it now. Two cylinder oiled on two wheels used for what you're after
as well as spraying waterbased finishes on wood projects. Oilless are
noiy and short lived they say but you know how "they" are.

Too late. Got one of these oilless ones already. I understand the
piston rings are teflon or graphite which is how they can be
"oilless." What is the best maintenance rountine? Release all air
pressure if not in use or can I leave it pressurized? How hard or
easy is it to replace those piston rings? I love the pneumatic tools.
I believe the cylinder liner is teflon. There isn't any pressure in the
cylinder when it isn't on, so you can leave the pressure up when not
using it. If you bleed the pressure to zero, you'll have to pump it up
again next time you use it - that's where wear would come from.
I haven't needed to replace any parts in mine, so I can't tell you how
difficult it might be. Looks easy from the parts diagram.
Yeah...I'm wary of that place. If Sears starts making tools in China, at
least I can walk into the store and either have the problem dealt with, or
introduce the manager to a new way of thinking.
well, let me modify what i stated. avoid the cheap noname compressors at
harbor freight. they do sell other makes, like ingersoll-rand and
cambell-hausfeld, which you can get parts for pretty easily. their brand
comes from anywhere where they feel like this week. mine actually comes from
italy i found out, and parts are 10-14 weeks away. so far, i've called 4
times, and they've sent me 3 parts, all the wrong one, and all taking
between 10-14 weeks to get to me.
to say i'm annoyed is putting it mildly. however, i've found that the axiom
'you get what you pay for' pertains in this case.

Are you looking at a tankless or tank type? You can get an AC powered
tankless type in a shape similar to the 12V powered one for $40 or so.
If you want one with a tank, there's a type with a hamburger shaped tank
below the motor with the foot print of a 15" TV, although it cost about
You have the idea.
You want a tank. It is a reservoir of compressed air. Filling a tire with a
small unit could take a very long time but the tank already has the air
available to be transferred.
There are many small compressors that are able to fill tires, do a quick
cleanup, power a nail gun and even small spray setups. They are not
suitable for air tools with repeated heavy use or constant use. I have a
Porter Cable "pancake" model that suites me fine. Takes little space, can
fit under a bench or cabinet, is light enough to take to the place you want
to use it. I paid less than $200 with a brad nailer kit.
If you have aspirations of painting cars with it, you need much bigger.
Nah....just tires, and blowing crud out of crevices, like certain tight
spots in my boat. I might use it once in a blue moon to try spraying paint
on a small project, but I'm not a big fan of spraying entire houses.
Tank gives much smoother air flow and a reservior for jobs requiring
blasts of air. The tankless type have very pulsy air flow and it
doesn't have much blasting power at all. The difference in peak flow is
like hosing something down with a hose vs dumping water with a bucket
you've previously "filled up" with the same hose.
The $40 unit is also going to have a light duty vacuum cleaner type
motor. $200 unit is heavier, made of metal and comes with a heavy duty
The first four articles on this page have a lot of good stuff about
Also, beware the phony "peak horsepower" rating on some compressors.
Things got so out of hand that class action settlemsnts resulted.
