co2 regulators

I am making a powertank clone to air up tires and run air tools and need a co2 regulator, is there anything special I need to get? Do I really need an adjustable one or should I get a fixed one? We have several tanks so I don't think i need the tank pressure guage. I have heard it is useless anyways. What pressure should I get for the fixed one? Thanks for the help!

If they work in the 85-90 range, can't we just use the ARB compressor then?

not enough air flow to run a tool off an ARB compressor.

Volume, air tools need aprox 4cfm, and the arb will not pump anywhere near 1/2 that My home 3 hp 11 gal tank can't keep up with air tools, it's a lil shy of 4cfm at 90psi

I have a 100psi fixed pressure regulator on my co2 tank. It seems to drop to 85~90 psi when the air really starts to flow, and I haven't had any problems running my impact gun on it. $27, call around to some welding supply places near you.

got the tank from some online aquarium supply place, dont remember the name.

If you're looking for a cheap tank, go to any fire extenguisher place and ask if they have any old SCBA bottles.
