Air compressor enclosure.

[jw33]

Decided to free up a good amount of garage space by building a small outside building in the backyard just for the air compressor. This was already a fairly quiet compressor, but it's also nice not the hear it fire up if I'm out in the garage tinkering around late in the night. All the electrical is coming from a 50-amp breaker through a disconnect and into a 30-amp (compressor) and a 15-amp (outlet/cooling fans) branch circuits. It's all underground and the disconnect is in the garage on the wall. Ran the air above ground at the base of the house slab mostly through 3/4 copper with just a short piece of iron pipe. Never again will I use iron pipe, too many leaks and they are a bitch to fix. It's just a 2x4 framed building with a shingle roof and Hardie siding. All of the walls and the ceiling have fiberglass insulation and that is 3/4 MDF on the walls. I used two cheap bathroom vent fans out of the ceiling to cool the inside and the intake muffler is built into one of the walls. Both can draw fresh air in, but it is all baffled through a couple of chambers built into the walls. When the door is shut you can hear it, but it sounds about as loud as the air conditioner sitting right next to it. Super quiet compared to the way it used to be sitting in the garage.

That's bad ass and something I always thought about doing. Reality is I'm too lazy and not skilled enough.

Wow, very very nice!

Looks like a prefabbed enclosure.

Looks great.

That's cool , but it is going to build some heat in there . I left about a 12 inch opening around the top for that reason .Hope you don't have a problem with it.

Did you pour the slab yourself.

It has two 60cfm bathroom vents that pull outside air in from the vent near bottom and blow it out of the soffits. I may add a pusher fan on the air inlet or maybe just a box fan to stir up the air inside when the compressor is running. My thoughts are that with it being such a small space the two fans can pretty much change out all the air on the inside and take the heat out with it. Who knows, we will see in the summer. I'm going to put a remote thermostat in there and see how it works. I poured the slab myself using quickcrete and one of those rental mixers from Home Depot. It was pretty easy.

That's awesome! I've thought about doing something with my compressor also but often wondered about heat. Heat will kill the motor. Is it up and running? What kind of temps are you.getting in there now that the Texas weather isn't in scorching mode?

[jw33]

I ran it today with a cutoff wheel which uses a fair amount of air and it really didn't get hot at all inside. The compressor got hot, but that's pretty normal when it runs. I think it helps that it's in a small space since the fans can change out the air quickly. I'm still going to put a remote thermostat on it at some point.
