It's not a medical grade tank, just a generic 20cf steel O2 tank with a standard CGA-540 valve. I suppose it's closest to a welding tank, though that's a pretty small tank. I do tank swaps at the closest AirGas.
It has a Western Medica regulator with flow meter I picked up from Craig's List
a few years ago for $15, seller didn't know what to do with it...
