Air Compressor Silencer
Air Compressor Silencer

1) Frame in air compressor in a Permanent
Location (2x4 framing)

2) Build interior walls using screen or
wire mesh, peg board
I used peg board it was cheaper

3) Cover walls using foam 1 inch thick

4) Finish exterior walls with peg board

5) I made the front as a door for access

Once completed put air compressor on rubber mat
Inside structure to cut down on vibration

Mind you its not finished so I am open to ideas
Thanks Everyone

For the foam use Sonex foam, it's a sound proofing material.

Don't use pegboard on the exterior. :nono:

Fiberglass is an excellent insulator and cheap too.

Dry wall will work, and not vibrate like pegboard. Cheap too.

Unless I am overlooking something one VERY important concern was left out, ventilation! If the compressor is to be enclosed in any small area, ESPECIALLY if something like insulating foam is used, then good ventilation is a must and even forced ventilation using a fan would be a good idea. Heat is one of a compressor's worst enemies and to enclose the unit in a tight insulated area might lead to serious problems, what was suggested is a good idea but ventilation needs to be considered along with it.

Air Compressor Silencer
If you are looking for a new compressor and have some extra money, look for a rotary compressor. The smallest one I have found, and not purchased, is 7.5 HP and will push 31 cfm/min at 100psi. You need at least a 60 gal tank and $3,800. The advantage is it has 100% duty cycle and is about as loud as a hair dryer. Not for the weekender but would be a nice to have. Good luck. j.L>

I'd make a 'doghouse' for a compressor if I had a shop... basically a small concrete pad connected to the building. On the concrete a rubber mat would minimize any vibes and resulting noise, and the 'garage' side would be sealed as the roof would be too.

At least the 'away from garage' side would be assembled with louvered slats (think siding with that's angled out so it lets air circulate but keeps air out) line this with screen on the inside to keep bugs out. Perhaps all three non garage facing sides would be like this if it's in arizona or another hot place.

It'd be setup as Compressor/tank with a shutoff valve, hard line through insulated wall and there another shutoff valve, drier/filter and psi gauge, etc.

WHen ever you enclose an air compressor make sure you dont restrict air flow to the compressor because it wont work as efficently if at all

Enclosing a compressor in a small area insulated with foam is going to create a serious heat problem unless it is well ventilated and simply installing some louvered panels on the sides probably will not be enough. These vents would need to be located near the bottom of the enclosure and then there would need to be vents at the top above the compressor, preferably the roof, so that hot air could escape and draw cooler air in around the bottom. A compressor radiates a heck of a lot of heat and not only will the air coming from the thing tend to be much hotter but I have seen compressors literally burn up because of poor circulation, and these were not even in an insulated room! I would strongly recommend a forced air type of ventilation especially if the enclosure is small, a fan in the ceiling with vents at the bottom should work. The bottom line is that if you insulate too well while trying to deaden the noise you may have your compressor become very quiet indeed!
