Trenching PEX for air to a shed?

Should work fine.
Actually should work good because the long length of line under ground will cool the air but it will cause moisture to condense. So long as you have a water trap at the shed end you will be good.

Run a conduit from the house to the garage now while the trench is open and you are ready for the future.
3/4" would be better suited for that run.
Run your cable and ethernet lines now too.

For a small shed?
Do you use air all the time? If it is just 100ft then why not get a hose reel?
Pex is just fine for shop air. Red and Blue pex is the same material and has the same temperature tolerance. As mentioned above, pex has a temperature limit. You won't be pumping hot air into the pex.
It is good to remember that a typical shop compressor does not output hot air. Yes the air is hot as it is compressed, but the surface area of the tank transfers the heat of compression to the surrounding area. Some compressors even have finned pipes to cool the compressed air prior to entering the tank. This gives a bit more capacity/capability.
I use shop air constantly from my 20 gal compressor. Did a bunch of paint rework on my plane last week. Not once has either end of the hose from the tank been hot, or even warm.

In my shop I did a "cooling wall" of up and down runs of copper with ball valves at each low point. Same concept as a vehicle radiator, kinda. That said, copper was cheaper back then. Then again, if I amortized whatever the cost was over the 19 years it's been in use.....well, pretty cheap.
Where am I spending a lot of money? As said somewhere else here, 100ft of 1/2 PEX is $30. Maybe a few bucks more for fittings, but the cost is minimal, much less than a compressor
Trench will already have to be deep, as the power will need to be 18 inches deep
Yeah, I'm adding a lot of conduit already, which is why I'm thinking of adding the air, the trench is already there
I like power and networking
And snake it across the yard and through a door? Eh
What are dimensions of this shed? Go bigger than you think you will need. IMHO.
12x16 with a 5ft porch, I plan to store some junk at the back but have a nice workbench in the front outlooking the porch area, will be a good space for small projects, I can work on them and leave them there for as long as I want, without taking up space in the garage
Of course 240v, I'll probably throw in a 60a panel on the outside of the shed. This way I can run my welder out there if I need to
Yep a 9000 BTU 240v mini split will be in there
You should go 16x16 or 16x20. Honestly. You will see how fast it fills.
Don't allow wife stuff in there. Like a camel's nose under the tent!!
Yeah let me just go ahead and demo the 4 inch slab that is poured already
Yeah, go 6-8" slab, run the conduits up through the new slab.
hahahaha kidding of course
What's the air for? Cordless tools can do most of the work. And cordless inflator is great. Set the PSI and wait for the beep. Or at least the good ones like Milwaukee can do that.
I have never seen a cordless blow gun can you post one up?
I have one for my audio stuff
125psi ? @ 10cfm?
