Room in shop for air compressor??

[Repsolracer22]

Hey guys. Got a new shop for our powder coating business. It's nice and roomy.

Has a room in the back corner. Needed a wall put up to completely close it in, and needs door replaced. I already did the wall and door will be tomorrow. My question is, I'd like to put the air compressor in here. There's a nice lean-to already built right outside that previously had 2 compressors in it. But I just bought a brand new IR 80gallon 25cfm compressor and it gets delivered tomorrow. I kind of want to keep it inside if possible. So I thought this room would work.

So the shop is wide open clear span 40x65. And this room is in the back corner. I'd like to use the room to store powder and put a dehumidifier in there. I assume I can put the compressor in there too? I know people like compressors outside because of the noise but I'm looking for some solutions to that problem. I'm going to mount the compressor on thick rubber feet. And maybe on the inside framing of the wall, there's some noise dampening insulation maybe? I don't want anything expensive like spray foam. Just want it as quiet as possible.

Any ideas?

You could use roxul acustical fire batt's for the insulation they are desgined for sound attenuation, they 31/2''x 151/2'' x 48''.

I second the mineral batt soundproofing insulation, it works very well. Clad the outside with 2 layers of 3/4" drywall and you are golden, used that to keep our drum/jam room quiet a few years back. Just make sure your not going to overheat the compressor.

is there going to be a problem with a dehumidifier in the room as well as the compressor? I cant think of any issues that would come from that, but just wondering. I plan on using the room to store powder, maybe a shelf for oil filters, oil, misc parts, and the compressor and air dryer.

how would you overheat the compressor? the drywall is already up and I went cheap and got the thin ****

although I don't have drywall on the INSIDE yet. so I could get some thick 3/4" stuff for that. hmmmmm.

the compressor is a 2 stage IR 80 gallon. so its not one of the "quiet" compressors. I have ordered the anti-vibration pads for the feet and I will definitely get the Roxul insulation. How thick should I go on that? It looks like they are sold in 2in thick pieces. Maybe double up and go 4"?? And how do you install those batts? do they have paper backing with wings to staple?

Fill the wall cavity. It should come in 3 1/2" bats. Just friction fit between the studs.

The door opening sure looks narrow, at least from this picture it does.
Hope the compressor will fit through ok without a great deal of struggle.

You could also add a layer of the thicker stuff over the thin ****

the opening is 32-33" which is fairly normal I believe.

Heat of compression is real, look at the big fan within the pulley that blows air across the fins in the pump casting and the interconnect tube. The motor also generates heat and must be cooled. All that generated heat must go somewhere. If you have a well insulated room with no airflow then the room will heat up, blow hot air across the cooling fins, compress hot air making it hotter and it is a vicious cycle till something fails.

You need some source of air into the room and a way to remove the heat.

no neat sig line

One of my former bosses told me he once saw a well sealed compressor room made of cinder block that was sucked in so tight that the blocks we're separating and you couldn't pull the door open. Make sure you leave some way for air to get in.

I've heard that if you remote the air intake to the outside and add a larger muffler you will reduce the noise by 25% or more, as a lot of the noise comes from the air intake, I've not done that myself yet but there are threads on here describing the process.

I will do it with my new compressor and probably use black iron or copper depending on what's available on hand and then add a bigger muffler on the outside.
