Shop air compressor wont put out more than 110 PSI
I have some extensive runs around the farm of air in PVC, and just 1/2" sch40 at that, BUT,
one where it's buried 36" or more underground in ditches between buildings.  I used PVC underground
to have no worries about underground leaks from fittings, but everywhere it surfaces I bring
the PVC aboveground it is encapsulated in a larger diameter metal pipe from 24" underground to past
where the fitting converts it to metal pipe.  This is done so any shards from a PVC burst will
be encapsulated by the surrounding metal pipe.  I have almost 6000 feet of underground runs
done this way around the farm and they work great and are also safe.

Using PVC for compressed air is not something I'd do nor recommend.
In fact, I would strenuously recommend you NOT do that. Compressed
air and PVC is a time bomb waiting to go off.

Here's what OSHA has to say about it...

Here's a few PVC vendors. Note that both have notations about NOT
using PVC for compressed air or gases.

ABS pipe is OK to use. But, not regular Sched 80 PVC.

But, its your life and your body parts - not mine.
