Eric, what were the demensions on them? I know you could use them for air tanks, like with a compressor.... 
Regulator would be no problem.
And if I remember right from my biomed days, they are pretty narrow. That might just fit under the floor board of say.... an XJ.

They are slim and long I'll measure and let you know tomorrow. I'm thinking about as big around as one of those Canadian beers Bill was drinking. Maybe we could trade for something
Great idea, but.........
Those look like 'E' cylinders.
They are 02 tanks and are meant to be filled with 02. I doubt you are gonna find anyone to fill them with anything other than 02.
Also, the regulators that fit those tanks are meant for 02 also.
Better off finding some SCUBA or SCBA tanks that have recently been hydro and visually tested. Or you could get an old CO2 tank and find a cheep reg on ebay or the internet.

The purpose-built regulator adapters on those bottles are going to pose problems... You would need to use the specific regulator for them and that wouldn't be too helpful. IIRC though, there is a threaded fitting that acts as a regulator bypass for use with portable ventilators/CPAP. You might be able to get them to work, but good luck getting someone to fill them.

If they're O2 bottles then they're probably designed for ~2500 psi service pressure. That is the only way that you're going to get any significant volume out of them, high pressure.
If you can get the valves changed to CO2 service valves then you can go with that gas. They'll probably want to hydro-test them at that point too. According to the wiki page the gas to liquid phase change happens at about 1450 psi (@ 70*f), so the tanks would be over-rated for the application. Shouldn't be a problem except with the un-educated and likely the wallet pain.
At the end of all of that I'll guess that a Powertank purchase is more economical.

Eric, here is what you need.

Just swap it out at any place that has em, like praxxair, or whatever. You dont need a 'powertank' or any of that fancy stuff. The prices on those tanks are a bit ridiculous.
The above tank, with a cheap 100-150psi regulator, does the exact same thing, but its not chrome. This is the kind of tank I have. You dont have to wait to have it filled, just drop it off and pick a full one. 28 bucks for a swap out.
You can still get me one of those oxygen tanks for my OBA compressor though...

Power Tanks are like so many 'overland' bits of kit - overpriced. They are nice, but all I need is to fill a tire or run an air tool. Pretty is not important. I found a GREAT solution:
Beverage Factory sells tanks for $86.40 and an upgraded regulator for around $55.00
A trip to Harbor Freight (I know... I know...) yielded an air ratchet, metric socket set just for the cruiser, extensions, and an air hose kit - all for less than $80.00
Works great. Costs much less. Yippie.

I found the same kind of deal at a local Beverage Distributor. They sell CO2 by the pound and were able to sell me a 15lb bottle & regulator for $150. Fill-ups are $12 or so.

I bought my 15 lb C02 tank of craigslist for 40 bucks IIRC, got the reg of the internet for 40 bucks and had some hose in the garage.
turn key for around 100 bucks.
I recently found a SCBA harness (like one from the fire dept) at a yard sale of all places for 10 bucks!
So i put the tank in the harness like an actual air tank. it fit with some tinkering. Now, I have a backpack mounted air tank that I can carry from tir to tie and car to car very easily.
beats the hell out of a $400+ Powertank system!!!

that regulator has a 55-65 psi relief pop-off valve, so your working pressure is what 50 psi? that cant be enough to even turn a harbor frieght ratchet can it?

I use a small/compact fixed regulator at 150 psi. It has no gauges, or adjustments, and work great for me. I like that it doesnt have a lot of stuff to knocked around hanging off of it. I do wish it had a high pressure gauge so I could more easily tell when its getting empty.
I wouldnt go lower than 100psi honestly, but I do use air tools all the time with mine. If you just air up, I guess it could be ok.

Once you figure out how to adapt them, the'yll work fine. The challenge will be draining the water out of them from time to time.
