Post your enclosed air compressor rooms...

[Bad00SS]

I'm drawing up the plans for my 32 x 28 additional garage and I want to quiet down the big stand up compressor. I want to build a closet in the corner to stick it in. I need some ideas. I was thinking about drywalling it in real nice with a door on it. Maybe use some sort of insulation on the inside to absorb some of the sound.

I just built one, well framed it up. So far I'm happy with it, my new compressor will fit in it on a pallet, but just barely.

I think its 39"x9' but I plan on putting a dust collection system in there also. I'm probably going to add some venting and maybe a temp controlled fan as well.

I also plan on covering it with insulation and something like dyna mat to sound proof it as much as possible.

I'll try to get a photo and exact dimensions for you tonight.

Edit:

I'll add that most recommend building something outside to put the compressor in. That wasn't an option for me but might be for you.

Just getting it behind a wall kills most of the noise (any wall). Airtight room helps a ton.
sheetrock helps. Google homasote. That is a sound deadener, but it looks a little combustable compared to some other options. I used an old exterior door on mine that we had replaced, and I think an exterior insulated door is pretty important.

If you want to go farther than that, there is much interesting reading on soundproof rooms on the internet. It's a fun subject.

We built ours with a ventilation fan on a thermostat.
You also have to consider what to do with the compressor water condensate.

Mine is just big enough to house the compressor, I think 30" x 30". It has a 28" door that I still need to install. I wanted to install an exterior-type door, but I can't find one in 28" size, so I'll just do an interior and put some type of insulating material on the inside, maybe acoustic foam. The closet walls are insulated with fiberglass batts and the interior walls are double sheet rocked with green glue between them that was leftover from a previous sound proofing project at our condo. The closet ceiling is left open to the attic, so temperature is not an issue. The rest of the shop ceiling is sheet rocked and insulated. A true test will be when I get the door on, but it already helps a bit in reducing noise.

I built a 5x10 add-on outside of the garage for mine.
it's gonna serve as a "shed" too.(winter tire , shovel and other miscellaneous gardening stuff)

2x4 wall and fully insulated (R12 wall, R40 ceiling) and a small 500w heater to keep it over freezing temp in winter.

The work in progress... It's approximately 4' by 8' and built with standard 2x4 construction with insulation. It will also serve as a warmer than the doghouse place for the pups.

Lined with QuietBrace and insulation, 1 1/2" thick walls on the back side facing the tool room. I just put a thin door using left over Quiet Brace on the parking side, not that worried about sound levels there

I built a couple of short walls, connected by a 45 degree wall in the corner near the overhead door.

I have 13,5’ ceilings in that garage, so I cheated a little on the compressor room height so I could have a second story for storage.

I think I insulated the walls with regular R13.

I got a cheap, outward opening 36” door from Menards on clearance and mounted it on the 45 degree wall.

Leave as much of a gap under the door as you can for air circulation.

My 5hp, 60 gallon throws out a lot of heat when used heavily, but an inch and a half gap over a 36” opening seems adequate.

You will need an electrical disconnect at the compressor, as it will no longer be in the same room as your panel.

Mounting the compressor in the corner (5 sided room) with the angled door wall doesn’t loose much useable space.

I prefer this solution to an outside access only room, as, if you locate the regulator and ball valve in the room, you have to at least look at the compressor to give it “the eyeball” every time you fire it up.

I had a fiberglass blanket over a wire frame which worked well but removed it for something and just sheeted it over simply for now. I was going to make something better but its not bad. The blue unit is backup and demand and I leave the breaker off. The green 3hp under cover is the main with all the tanks plumbed together, its been a long time since I used the demand unit.
Its not great, not bad. A guy hets used to a certain sound, just enough to notice a bearing headed south in the motor a couple years ago.
Nut and bolt bin is removed with a pallet jack, the whole thing comes out in about 5 minutes.

Some great ideas here!
Geez I should put a barrier around my compressor to deaden the noise. The racket makes my skin crawl.
