Posted: Mon Aug 28, 2006 7:57 pm Post subject: How to quiet an air compressor?

I live in a duplex and my workshop is in the basement. My air compressor 

is very loud and I need to find a way to silence it, or at least quiet 

it down. Does anyone have any suggestions for how to do this? I have 

thought about building an acoustic enclosure, but don't know how to do 

this without harming the cooling and still letting air get in.

I'm not an expert on the subject, but I'm sure someone is. You probably have 

one of the diaphragm type of compressors They 'rethe noisiest. That's the 

same I have. I put mine outside in a tool shed behind the shop. Now the 

neighbors have to listen to it. If I were in your situation I would build a 

box around it and line it with styrofoam board. You might be able to cool it 

by cutting some louvers in the bottom and some more in the top. Maybe get a 

small squirrel cage fan or a bathroom fan with some ducting and suck the air 

from the bottom out the top. The holes might let some noise out but I'm sure 

it would cut down on the noise considerably. The other thing would be to get 

a compressor that is belt driven. They still make noise, but not as much as 

the other type.

That's my idea. Let's see who can add to it. Good luck on it.

Hi Todd,



One way that works is to replace your direct drive compressor with a 

belt driven one.  The belt driven ones are more expensive but 

naturally more quiet.  I got a really nice one made with "Eagle" 

brand for around $250 from the "Tool Peddler" in Portland, OR - near 

my home and shop.



Sorry if this is not the answer you were hoping for.  Maybe somebody 

else has that one.



Good luck,



Paul

My guess is that you made the same mistake I did... buy an oiless compressor. They are just loud by nature.

Todd,

 You can build a small (leaving about 3' all round the compressor) shed with acustic foam inside. The foam is similar to the waffle bed foam in that it has spikes that stick out into the room. Some has spikes that are only 2-3", while others stick out as much as a foot or more. The acustic foam absorbs a great deal of noise and even simulates the vaccuum of space.  

 It is used at Raytheon in all kinds of acustic chambers where they fire rocket engines, etc. Very very effective and not very expensive. Even the intake and exhaust duct can have the attach point come through a small acustic lined box. 

 A small fan in the exhaust duct will probably pull enough air for cooling. I suspect one could be built for less than $300.00, which includes a nice weather proff outside finish. A cheaper one could be built for much less. Just an idea.

Todd - Try one of these commercially made filter silencers if your inlet has 1/2" NPT. I got this one at Grainger and it works great even on my oilless compressor. It's not silent, but it's MUCH quieter.



Around $20 if I recall.

I am a single guy with an understanding girlfriend. I am building my plane poolside on my on my lanai. I put the compressor inside the house and run the hose out the sliding door to the lanai. Since there is no one in the house it really doesn't matter too much about the noise. When my girlfriend is there she knows to expect the compressor to turn on from time to time. No complaints so far from neighbors or girlfriend! I was married for 25 years and this would NEVER have worked with the wife.

If this is the one problem, then maybe you need to build a "muffler"

for the intake and exhaust sides. Need not be anything fancy. Here's a

concept. Your mileage may vary. };->



- Poke a piece of sheetmetal a/c duct, about 1' diameter by 1' long or

so, through the wall of the enclosure.



- Cut (say) 4 disks of foam, sized to fit into the duct. In each one,

cut off a segment about a third of the way across the disk.



- Arrange the foam disks with the open segments in an alternating

fashion inside the duct, one after the other, securing them with

long-ish sheetmetal screws from the outside.



- Use one of these assemblies for cooling air in and one for air out.

Place them as appropriate to ensure air flow -- either via natural

ventilation or forced air. Add a fan if you should need it.



I hope this helps. Good luck,



Ihab

Bon Jour, 

  I heard that u can use a CO 2 bottle with a regulator for spraying. The bottles are pressurised around 800 psi and the co2 is anhydrous (no water trap needed). Best thing is it's quiet!

That is one of the systems they  use for airbrushing.  A real plus is there are never any water droplets in  the paint. and you don't need an expensive dryer on the pressure  line.
