One thing that has always bugged me about air compressors is that
they're noisy as hell. (At least the big Sears kind, which is what we
have at work.) That's why I've never bought one for my home workshop.
Yet when you visit the automobile service station you never hear the
damn things, just the whizz of the impact wrench. I'm going to ask the
local mechanic on my next visit but I think I already know the answer:
it's outside and it's an industrial unit. Translation: overkill and too
expensive for the home shop. Correct?
So is there anything that's truly silent or very nearly so for the home
shop? I'd really like enough CFM to drive a small sand blaster with it
but not if the compressor is going to have SWMBO and her minions running
me of the reservation as my workstop is in "my" half of the two car
garage, directly below the living space.
Suggestions or recommendations?
I also have a 4 gallon tank. Could I hook it up to the tank to use with
something bigger? I understand it will take several minutes to refill the
tank, so the rate of use will be pretty feeble, but any reason it wouldn't
Hey, I have the "affordable" Porter Cable 6 gallon pancake. My ears
bleed when it fires up. I also have a 12 year old 25 gallon sears unit
in my shop. Likewise, my ears bleed when it fires up. The fact is, just
about any belt driven compressor that you have to oil is going to run
quieter. That said, ask yourself the question. Am I going to buy the
filters to keep the oil out of my spray gun? A small laquer job is not
worth breaking out the hvlp unit. Unless there is a chance of oil
getting in the gun and mixing ,or not mixing well at all, on my
beautifully crafted, expensive hardwood project. I am of the opinion
that compressors that you have to oil, are more at home in the
mechanics shop than the woodworker's shop.
Tom in KY, thinking about putting my compressor under the counter and
see if that helps keep the blood off of my collar. My wife thanks you
John B. and I do too.
Jun-Air makes some small "really quiet" air compressors. They are about as
noisy as a frost free refrigerator and really quite amazing, but their price
is a bit more (150%) than a typical pancake compressor.
I have one (4 cfm @ 60 psi pancake style) that I use when I'm doing power
carving in my hotel room or doing demonstration carving at shows. The first
time that I turned mine on I was in a cabinet shop environment, but off in a
relatively quiet corner area away from the mainstream work. The light came
on when I plugged it in, but I thought it was broken because I didn't hear
it running. Then I realized that air was coming out of the valve. Careful
inspection, and putting my ear against the compressor, proved me wrong. The
small air pulse released from the unloader when it is shutting off is even
louder than the compressor running noise.
I once used it with a Porter Cable brad nailer to do a job in an area where
excessive noise was prohibited, and it did just fine. It'll build pressure
to about 120 psi before it shuts off, so light nail gun use with it is
possible. If I had originally intended to use it for nail guns I would have
bought a larger one though. I had originally intended to use it only for
power carving and it's perfect for that.

We have a FINI brand small compressor that we carry for back-up work.
It's a model that requires oil and looks amazingly like the small
Senco pc1005 model. It's very quiet compared to the small Porter
Cable pancake type models or a larger Emglo that we use on the job.
It won't handle more than two guns at a time though and I'm not sure
if it could handle the sandblaster.
If you needed a larger model, could you just put it outside and run
the hose into the garage?
You are quite right about location. I work in a machine shop. Our air
compressors are outside. It has two advantages. It eliminates having to
listen to it and it's better for the compressor due to better airflow. It's
not at all unresonable to do that at home. Couple of holes in the wall, a
litttle pipe and a little wiring.
As you stated, that you want to run a sand blaster, and tat requires a
fair amount of "cfm"-cubic feet/minute, which means a large compressor.
I am a field service tech for Atlas Copco air compressors, capacity
and quietness generally (in less expensive air compressors) do not go
together, if price is important than a exterior location with sound
deadening material is the answer, however if you have the money or that,
and can afford to put some more with it then I would suggest looking
into a Atlas Copco oil free scroll (SF2) compressor, as I have serviced
many located in quiet work areas in a lab at "Shrinners Hospital in
Boston MA", at many "Lens Crafters" locations.
I'm not sure of there cost, I would guess around 4 to 5 thousand, they
are available in single phase (220-230) volts as well as the
commercially normal 3 phase (208/230-460) volt.
Expensive but very quiet, just about as big as a dormitory
refrigerator and not as loud as a pain shaker.
I have a June air or maybe Junair compressor and I can't really hear it at
all. It will run a nail gun but I don't use bigger tools. It is very quiet.
I understand they are very expensive. This one was a gift from my boss.
