Compressor location
I am getting a building given to be but I will have to tare it down and move it. I am wondering about locating my air Compressor. I was thinking of putting a lean to or covered shed and putting it outside. This will give me a workshop for wood work, motorcycle, smaller stuff.

It is 18x24x14. My son was going to get it, but is not doing so now.

No larger than what the building is, that is what I'd do. Build a small bumpout on it, insulate the room, add a means for fresh air intake.

I agree with Kevin, put it outside. The room it would take up inside, plus the noise, it's better off outside. Insulate the outbuilding well.

Noise was the main concern. Should I have access from the shop and the out side too. It is a medium size compressor that I used to use on my car stuff. A little small at times. But a lot bigger than my baby 110v compressor. :D

Mine is in an uninsulated, closed in, "lean to" outside. I put a switched receptacle to control it from the inside and piped it with std PVC and a HF water/trap regulator ($20) and plugged it in. Works great...

Outside in a little bump out room with a sloping roof would be the best. If you live in a freeze prone area I would insulate the room. Moisture collecting in the line as it leaves the compressor could freeze and cause the line to split especially if you did not use it for a few days during a hard freeze. As for PVC I would not use it. I have been told not to use it and I did any way only to have it split and blow out with out any kind of a warning. PVC pipe is great for water and CPVC is great for hot water. Even though the pressure rating is there you have to take in account for the heat factor of compressed air. As the temperature rises both PVC and CPVC drops in pressure rating exponentially. The couple of times that I had a blowout I looked at all of the splinters and bits and pieces scattered all around the shop and thought man if I or one of my workers had been standing close by a piece of it could have gone in their eye or something. As soon as I was able I replaced all of it with galvanized pipe.

Outside is best, insulate the shed - you and your neighbors will be much happier.

Fresh air intake is a must - and you should get an automatic drain (15.00 at HF)

I just built a room inside - 200.00 in materials with insulation vs. concrete and materials for an oustide shed.

Oh that's nice, and I see that you have built a water trap system on the wall behind it.

Steam Rdiator Water Trap
Now something that you guys may not know is to use an old house steam radiator as a water trap. You can pick them up cheap at building wrecker yards. They can hold a lot of pressure and usually all that is wrong with them is bad fittings and you will change all of that anyway. Plumb it so the air from the compressor goes into the bottom at one end and leaves at the top of the other. Depending on what type you find you may have to drill and tap a hole. You may even have to use a bung and this could be brazed on or silver soldered. Place it so that air can get to both sides and put a water trap down low at the outlet side or end, I have an automatic spitter valve on mine. Be sure to slope it about an inch toward the spitter. You will be surprised at how much water it collects.
