Could always ask the guy over at WabFab . . . iirc, he's a certified pressure vessel inspector, but I might be wrong about thatOriginally Posted by Robinhood4x4

He is and I'm sure he'd say the same thing. He's very skiddish when it comes to pressure vessels as he doesn't even like using fire extinguishers as air tanks.

If the tank says air only, it's air only. The fact that it's a composite tank might mean it can't put up with colder temperatures of vaporizing CO2, but in addition to that the internal intake might be incompatible with liquid gas, making it more likely to release liquid CO2 into your regulator or fill line.
As for using them as OBA tanks, well sure its possible (as long as you don't tap the tank, use the existing hardware) but it seems to me they would be much more useful in their intended role as high pressure tanks.

Scuba shopsOriginally Posted by Crinale
Yup, probably scuba shops. I <think> those might be small SCUBA tanks looking at them, but it's hard to say. No one would fill then without up-to-date hydro tests though.Originally Posted by Crinale
Regulating would probably end up being a 2-stage setup like SCUBA uses, where the first stage regulates down to 10 Bar, and the second stage would regulate to what you're looking for.

I'll probably do just like stated use the valving on them. I was just planning on using them as small tanks. Nothing i have would need that much volume anyway. Will probably use both now to get a little extra volume. The two will probably be the same size as the big red tank that i originally had set aside.
Thanks for all the good ideas and points.

For the record I am not a pressure vessel inspector, I actually design pressure vessels (and a lot of other stuff) for an industrial fabricator per the ASME VIII Div 1 and 2 code.
