Suggested 02 Bank Storage Bottle?

multiple 13s is way cheaper than a booster

multiple 13s is way cheaper than a booster

Maybe I'm looking at the wrong sites but:
The AL13's I've seen are $200:
Aluminum 13 (2L) Cylinder for CCR

AL80 is $270.
Thunderbird AL-80 Cylinder, Brushed No-Coat

Interesting, will check out the HP100 as an option. It might be discontinued but will take more digging. I definitely need to be careful with electricity and 02. Would people have any issue getting a used tank and getting it 02 cleaned (either steel or AL) or just start with a new tank for pure 02?

An al80 is not a booster.

These are boosters Oxygen Gas Boosters, Compressors and Systems

What does electricity have to do with anything? You might want to start with the Oxyhacker handbook before you go any further.

One AL80 source at 3000psi, AL17 target. (Calcs done assuming empty rebreather cylinder)

After 1st fill
AL80 - 2474 psi

After 2nd fill
AL80 - 2040 psi

After 3rd fill
AL80 - 1682 psi

You're only getting 3 goes before you getting less than half a tank.

If you don't want a compressor and a booster, just get another 2 or 3 sets of cylinders for your rebreather and get them all filled in one trip to the dive shop.

Hypothetically, I don't know how practical this is, but fire department SCBA tanks are rated to a lot higher pressure than scuba tanks. Since you're not planning to dive it, maybe you could use one of those? I don't know what they cost, new, but I have seen them for sale used on marketplace. Also not sure if they can be O2 clean, I just know you could get a much, much higher pressure, which would maybe let you get multiple fills to 3000

SCBA bottles are fiber wrapped so they only have a 15 year lifespan at most. Plus they are expensive.

Cheapest way is one or two AL 80s and a transfill whip with a gauge. I'd go new, used just isn't worth the hassle in this situation.
Easiest way is several 2L O2 bottles.

except nobody is going to filling them with >3k O2 anyway

Seems like the chances of getting an HP filled to "full" with 100% O2 are slim...

So use an LP98 or something.

@sea_ledford Wasn't sure about the lifespan issue. There's been some arguments about that over in the Avelo thread, and I never was sure who was right.

@rjack321 I'm strictly an air diver at the moment, so such things as what you can put high levels of O2 in is outside my knowledge, I was just saying that'd be good from a pressure standpoint. Idk why nobody would fill those that high with O2, or for that matter why they wouldn't fill steels to that level, if you care to share.

What about a commercial tank as supplied by your local gas supplier? You can rent or buy the cylinder, use a welding type medical regulator, and get bottles from 40-200+. When you need more you just swap bottles.
