Suggested 02 Bank Storage Bottle?

[Dont_Hold_Your_Breath]

Getting to the shop for 02 for my CCR is challanging for a few reasons but that combined with often diving in remote locations (no flying, only driving) means I'm looking to make fewer trips to the shop for 02.

Is my best bet to get a brand new AL80 that's 02 cleaned and use a transfer whip to equalize the pressure to my smaller CCR 02 tank? With equalizing the pressure between an AL80 and an AL13(2L) I'm guessing I could get ~3ish fills. I've seen some medical 02 bottles around that aren't expensive but that doesn't seem like a great way to go and I'm sure many others have done this before. If I have to buy a new AL80 then that's fine.

What CCR? Using a 3L will give you 50% more O2 right off the bat and a "short" transfill is still a decent amount of gas.

Med O2 bottles are at 2200psi and small. You may want 2x al80s. Get yourself a needle valve and a gauge to slow your fill rates way down.

what about a single steel hp120?

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

yea, agreed. i got one filled at a shop to 3500 once but it's probably not standard practice for a good reason

Most shops wont fill O2 more than 3k for a reason. Go with the largest LP cylinder you can find and rock that. Get a nice transfill whip and go from there.

Other option is to find a nice little mini booster to take with you and then you can use whatever cylinder you want. Most mini boosters dont like when source gas is below 650psi...

Apprecaite all the responses. Rebreather is a Dive Rite Choptima.

Looked at the mini booster and all the ones I foudn were pretty pricey ($1k+). I was under the impression that you don't want steel and pure 02, was I wrong about that? My understanding is that they may rust faster with pure 02 and/or rust could potentially cause an explosion thoguh this is all theoretical and I'm not sure what's practical.

O2 is supplied everywhere in steel bottles. It's fine - just keep them dry inside.

Aluminum is actually more flammable than steel by A LOT. Which is why aluminum medical O2 regulators were heavily recalled a few years back.

Basically every O2 bottle you get from a gas supplier is steel - many of them decades old. Steel is not a problem.

Most normal rebreathers also run a steel O2 bottle.

I would second getting a booster and a decent shop compressor to run it. I've run mine off a HP100 for doing a parking lot fill.

Will also depend on what local dive shops are willing to do for you on large 100% fills. You will still be tied very closely to the shop for the fills, just not as often. At that point have you considered just getting multiple AL13s for for the Choptima? No transfilling needed. Even with a booster I still have 3 sets of rebreather bottles.
