Question on air compressor

That was a big concern - the motor generates a lot of heat.

I tore the unit down enough to get a look at the compressor, and it turns
out the intake is essentially the same space as the underside of the piston.
I didn't see any practical way to create an intake muffler, so I reassembled
everything. I am thinking of placing the compressor in the crawl space and
the tank in the garage, so the noise can be exiled while the maintenance of
the tank can be done in the garage, but I fear the noise will be spread into
the house if I'm not careful.

Sprayers take a lot of flow. If your wanting to spray stuff like that, just
buy an airless paint sprayer.

Heavy duty impact tools, by contrast, require high pressures and
you need a dual-stage compressor for that. For example I have
a 1 inch chuck impact tool. I rarely use it (very rarely) but it is
strong enough to break axle nuts free without having to jump up
and down on a cheater wondering if your going to snap your
breaker bar. However, 120psi is about the -minimum- it requires
to operate.

What the small compressors are sold for is running stuff like
nail guns, so you can use a nail gun to nail your new deck together.
But that's about all they are useful for.

A small auto muffler can be modified for air compressor usage. Did that
back east...

Sounds like just the thing! How did you fit it to the compressor?

Consumer quality compressors now have rating numbers, with a chart to show
what tools require. The 8 cfm 140 psi single stage noisemaker I have is
rated "4" and works the 1/2 inch impact tool I'm using, for the casual pace
I keep at home. It would be completely inadequate in a busy shop. It
struggles to keep up with a conventional spray gun and I haven't had the
nerve to try it with an HVLP sprayer.

To get rated impact out of any tool requires delivering rated pressure at
the tool, and 1/2 inch hose has a bunch of drop for air gobblers like that.
To get a crank bolt loose with the 500 ft-lb impact I had to put the
regulator right at the tool and run the hose at 120-140 psi. That did the
job, though. Axle nuts don't resist even with the regulator at the tank. I
don't know how I got along without it.

I have this compressor. It was good for blowing passageways
in carbs or cleaning off furnace filters. not much else. i got
it when it was half price so it's ok for that price. it's not much
good for blowing up air matresses as it doesn't have enough
cfm. and lots of noise when it's in the house.
i wouldn't get it unless it's all you can afford.

Thanks to all who replied. I think I will pass. The idea of
renting it at Home Depot or someone else was brilliant. Might
cost more over the long run, but I do not need to store it
anywhere...

Cheers all!

I have a 3 horsepower twin cylinder belt driven with a 20 gallon tank.
It is located deep in my basement, underground, and I just run air
hose to my working spot ( I made a feed-thru to get the hose outside
).

This is the _minimum_ I would recommend to anyone. I put it in the
basement to minimize noise, but mostly to conserve space and protect
it from the elements. It is on its' own electrical circuit ( I had an
electrician make a circuit just for this compressor ).

I've use all air tools with this, and an HVLP spray gun, and it works
fine. It didn't cost more than $300 IIRC, so was a good investment.
You could spend that much on 1 electric tool.

If I had it to do over again, most likely I would go for either more
HP ( 5 ) or a larger tank, or both.

Text description below sounds like a home duty compressor for occasional
use. Should work.

Hi there, fellow car enthusiasts!

I am looking for a simple air compressor to do simple house work,
nothing too heavy duty. Also, I do not really need to have full
continuous operation as long it can spray a few things in, say,
15 to 20 seconds burst, like: deck stain (light oil base),
oil-based rust proofing (like light oil Rust Check sold at
Canadian Tire and elsewhere) and latex paint. I am not interested
in using it for more powerful air tools.

I am considering this air compressor from Canadian Tire. Would
this do the job?

Thanks again,

Dear Frank,
I think your original post sounded like occasional use.
