Underground air line - The 1947 - Present Chevrolet & GMC Truck Message Board Network

pwdcougar · 04-03-2021, 02:52 PM

I’m planning a pole barn about 45’ away from my existing garage. I’d like to leave my air compressors where they are and put an underground line to the pole barn so I don’t have to listen to them and to save space.

Anyone ever done this? Is it possible?

Thanks

pvc should be sufficient but copper would probably be better.. you could even consider burying larger pvc and pulling some 3/4" or 1" flexible tubing thru for serviceability..

burial depth and materials may vary by location so may want to consult with local plumber for advice, code info, etc.. especially if your trenching for any other utilities..

may also want to consider a storage tank in the new building to stabilize temp and air delivery.. of course good FR(L as applicable) and any number of modular plastic quick connect tubing options for distribution manifolds.. various options for mounting couplers..

I even ran full copper distribution in a building once that owner fully polished afterwards

I had this same idea for the farm and I'll probably do it when I trench the ducts for underground power.. good luck!

Interesting writing style from the previous poster.
PVC rots in sunlight so think if it's exposed at any point. PVC bad. I'd also wonder about where water might collect at low points.

we have underground line running from the compressor to a inground hoist,been there for 40 years,no problem what so ever

I have a 1" rigid Galv. pipe buried from one garage to my big shop that has been there since 97' without issue. It is roughly 20'. It is probably getting time to dig up and replace though since it is the lowest point in the system

I've been considering the same thing from my main shop out to my pole barn..
Gonna be running some 110 out there anyway for lights and plugs, and want to run airline at the same time ..my compressor is under a side shed on the main shop so pole barn is end of the line..
With it running underground it will be the lowest point..I was worried about it turning into a water trap..
So I'll probably add a reservoir tank out there with a condensate drain..and only valve that section in from the shop when needed..

I did this at my last shop and it worked great. Buried 2" PVC electrical conduit with LB's at each building, ran a fish tape and pulled an air hose through from one side to the other. This way if there's ever an issue I can just pull a new hose through and good to go.

Notch, that may be the way I do mine...I could pull my 110v wire and hose at the same time..

Thanks everyone! Now all I need to do is build a pole barn garage!
