Ultra Quiet Air Compressor

[itsme_Bernie]

I got mine from a decommissioned Gast O2 pump, added the pressure switch, and a small two gallon tank. I have a 5 gallon alternate, portable tank from an Auto parts store that I fill from it, hose to hose, using this doohickey:



The valve really makes it much easier to use, even though it already has quick connectors.

How about just building a box with Styrofoam insulation to make any of them quiet?

There are several reasons, but first on my list is the fact that it won't work. Styrofoam won't keep a noisy compressor (or anything, for that matter) quiet. What it will do is suppress some (and ONLY some) of the high frequency sounds put out by the compressor. It will do NOTHING to suppress the midrange or (especially) the lowrange sounds. It would be one thing if the sounds put out by a typical compressor was all one frequency - but most sound sources are comprised of a surprising number of sounds, all with their signature frequencies. That problem alone is enough to make me rule it out as a possibility. But the other issue is one Ron brought up - where's the exhaust gonna go? It will need to go somewhere, and when you cut a port to let it out you're right back where you started.
Sound attenuating is a completely separate issue from soundproofing. Soundproofing can ONLY be accomplished with a combination of two factors: dead air and limp mass. Several years ago I spent four years building my own soundproof recording studio at a cost of $22K. It wasn't perfect but it would contain 90dB at 50HZ. Any louder than that and there were problems in the family - the bedroom floor was 36" directly above the studio's ceiling! By the way, I can't tell you how many teenage rock musicians I've met who are convinced they can "soundproof" a garage space by lining it with eggcrates. The laws of physics were pretty much set in stone a little less than 14 billion years ago, and they haven't changed much since...except for one guy who changed water into wine, walked on water, and later was able to rise from the dead.

Seems to me if you need a quiet air compressor (and I do - that's why I was ecstatic to see the original post), then just buy a quiet air compressor. That's my story and I'm stickin' to it!! )

Well, I just put this one - http://www.amazon.com/California-Ai...=8-5&keywords=california+air+tools+compressor on my Christmas "wish list" for the wife to see. :thumbzup:

We'll see if she gets the hint. :biggrin:

Wow! That's a fun compressor! I hope the wifey gets the hint...) It's a little large to get one of those Amazon drones to deliver it. Hmm, maybe they could get TWO drones to drop it off at your front porch...:think1:

We bought a California Air compressor for my wife's jewelry business. She only uses a toot of air to blow small parts clean. It is pretty quiet. Not as quiet as the Jun Air units we had been using. They are hard to hear coming on! But,they cost a fortune,and give very little air. They were fine for our intended use. The Jun Air units sound like a refrigerator running. They look just like the Gesswein unit shown above. May be the same,re badged. I found 2 used ones in a picture frame shop. We used them for years. The framing shop just used them to drive small nails in making picture frames.

Any conversation and you won't hear them running. Teeny little sewing machine sized motor embedded in their cast iron heads.
