I have been thinking about putting my air compressor in the crawl space of our house. Barring any sound issues (we have decent insulation), can anyone think of a bad reason to not do this? I have thought about the humidity and needing to drain the tank more often. I think I can deal with this by just draining it often enough.

If it’s one you have to maintain by adding oil, cleaning filter, etc it could be a bit of extra work to get to it.

They put AC units in crawl spaces, so I don’t see why a compressor wouldn’t work. Are you talking about crawl space under the house or in the attic? If up in the attic, depending on the construction of your home, you may have vibration issues (as well as sound issues) that might cause problems with the finished ceiling.

Just make sure you can get at it easy enough to drain the water and/or service it when necesssary

How easy is it going to be to get to it to drain the tank? Most crawl spaces aren’t that big.

I drain my tank daily, so it wouldn’t work for me.

You can do whatever you want, but I would be worried about critters chewing on wires and hoses and making nests where they don’t belong. I also imagine it might be really damp under there.

Crawl spaces are ventilated too, and there COULD be some issues with moisture. I don’t think I would out one in there.

Thanks for all the replies.

The tank draining issue is the biggest one that I can think of. Luckily, where I would put the compressor, the crawl space is about 7 ft tall and has almost a normal size door. That being said, it still will be a pain to go in there to drain it regularly.

I also thought about the moisture problem. We do have plastic down to act as a vapor barrier, but it is vented to the outside, so I probably would get more water in the compressor than I am getting currently.

Sounds like a good idea to me. I would plumb full tank pressure to where ever you’re using air and regulate it at that point so as to not have to go into the crawl space to adjust the regulator for varying applications. You can get an automatic drain that will open for a user specified time and a user specified frequency for less than $100 so you’d have to lay eyes on it very infrequently. Turning it on and off should be made possible remotely so it doesn’t run unnecessarily if there’s a minor leak, or if someone is asleep above it.

Put an automatic drain on it.

7 feet! You could put the compressor on an elevated and insulated box that hung from the rafters, or was freestanding. Remove the bung from the tank and take it to HD and I’d bet you could get fittings and piping to make a long remote drain that runs to outside where you could reinstall the bung and petcock. You’d have to factor that volume of air into how long it takes to cycle back up, though. You’d still have to go down there to adjust output pressure though. Get a cat to handle the mice.

Hey – look what I just found!

7 feet?? Hell, I’d make a shop out that space!

Well, when I say 7’, it goes from 7’ to 3’ in about 13 feet, so it really wouldn’t be usable as a shop. I sure have thought about it though.

I will look into some sort of automatic drain. Thanks again.

I’d put my compressor in there. With that Radon barrier/vent, humidity should not be a problem.

You can use pipe to make the drain go where you want and then terminate it with a ball valve that you can access easily. Or build a small lean to against the house/shop and do the same. I had mine in what looked like a dog house for years until I added onto the shop and planned for the compressor to be in a separate “closet” with decent access.
