Years ago I worked with a guy that tried this so he could run air tools
on road service calls. He tried a typical welding style gas regulator.
He found that this type regulator was not capable of flowing enough
air at the CFM used by any but the smallest air tools. There may be
other types of regulators that are, it's something to be aware of
if you decied to try it. If you are just thinking of using it to
run a nailer or other low-CMF tool, it would probably be OK
with the welding gas regulator.

plausible, and wrong." (Mencken)
I have seen someone selling a CO2 system to run tools.
Some sites say "never use CO2 for tools" so who knows?
I'd use a compressor-type regulator,you just need the right fittings to
mate with the tank.At a place I worked,the expanding foam system used to
make custom-fit shipping box inserts was powered by a tank of nitrogen.
JAC PAC,that's what I was trying to recall!
IIRC,they designed their own regulator.
CFM requirement is very important.Stuff like grinders,cutting tools,and
impact wrenches use a lot of CFMs compared to a brad nailer.
CO2 may freeze up the tool,too. IIRC,nitrogen doesn't do that.
How about maximum inlet pressure for an air compressor type regulator?
A compressed gas tank can have upwards of 2000 psig. An air
compressor typically maxes out around 110 - 150 psig or so. I'd
sure want to check before I connected a regulator to a compressed gas
No dumb questions, just dumb answers.

Back in the days when I used a scuba cylinder to supply shop air, I just used
the 1st stage of a diaphragm type scuba regulator (an old US Divers Conshelf, as
I recall) to bring the pressure down to something reasonable. Diaphragm 1st
stages are completely adjustable from 0 psi all the way up to about 140 psi.
They can supply that preset psi with a cylinder that is filled anywhere from 140
psi all the way to full, maybe 3000 psi for an aluminum cylinder, or 2250 psi
for standard steel tanks.
So I had the tank, the first stage and a BC inflator hose screwed into the first
stage that accepted air chucks, blow guns, etc into it's quick connect fitting.
Worked fine... and the air was as dry and clean as can be.
Thank You For The Input. I Will Be Trying It Within The Next Couple
of Weeks With A Steel Tank of Compressed Air From A Welding Supply
House. I Am Going To Use A Regulator That Can Handle The Input
Pressure of The Tank and An Adapter To 1/2" NPT For My Application.
I Will Be Sure To Let You All Know How It Went...Check Back In A
For small jobs,it would work.
they now have a portable system that uses paintball gun tanks filled with
CO2,for air nailers.
You also could use nitrogen or compressed air;paintball specialty stores
would be able to refill for you.All three gasses are now used in PB.
