air compressor silencer
Posted by jinithith2 on Sunday, October 30, 2005 7:44 PM
Yesterday, I was browsing through an issue of FSM from the year 2000, and I came across this ad for a compressor that was "super silent", a little less than 50decibles. Naturally, I had to go to my science encyclopedia to look it up. so in a sound chart across 50db. I find a person shouting with his face all red and purple. to make sure, I read the caption and it said shouting. Super silent?
HA! yeah, you have the "super silent" air compressor and you would go through a 20-30 min painting session with a person shouting in your ear with out going insane? tha was the last straw, so I built a simple silencer.

I poked around the house for a small container that would fit my compressor, a Testors Mighty Mini. I found a .50 cal ammo can that I had bought for 8 bucks at an airshow so I took it to my workshop and did the following operations:

1) lined the walls with old clothes, towels, etc.

2)put in my compressor with the cord hanging out of the opening.
since my compressor looks like a box, I put it on its side.

3) screwed in the a/b hose

4) cover assembly with another towel

5)shut lid of ammo can. the hoses and cords shoud be together and hanging out where there are no lid lips (will post pics soon for clarity)

expectations soaring, I turned it on and voila (can't find accent marks!)! my roaring monster was a purring cat. Try it! it really does help. as for the tube beng constricted from the lid, it is no problem. the electrical cord "lifts" the lid just enough to let air in and right back out the hose freely.

Proof of success: when I asked my mom if she had heard me spraying, she said no and said "what spraying?" either she was kidding or my project was a success!

I might wanna submit this to FSM reader tips!Big Smile [:D]

oh yeah! good point!
When I was a/bing for about 30 min or so, the assembly started to get warm. shut it off and leave it alone for a while to cool it down,

Heat would be my major concern. The Testors Mini's probably not as big of a deal, but some of the larger diaphram-driven compressors get hot enough to fry an egg on (hence the thermal shut-off switches). My old Paasche 500D got hot enough to give you a third degree burn if you put your hand on top for too long.

Glad it worked out for you!

try going to radio shack and buying small electric fans. I have made enclosures for automotive stereo amplifiers before and put theser in the ends to keep it cooled down. Those amps get hot after a nice long jam session and not much air moving across the heat sinks!
