Masterline Oxygen Booster

[FLDVR]

If anyone sees a used one, please let me know.

There was just one on E Bay, I did not check to see if it sold or not.

A membrane doesn't give you 100% oxygen boosted to 3500

WHY ON EARTH would you want to walk around with a cylinder of 100% o2 boosted to 3500 psi???? isn't that like a mobile oxygen bomb???????

Better 3500 than 10,000...

I get my O2 delivered from Air Liquid in 50L cylinders at 300bar. as long as I maintain a 5 cylinder cascade I can always transfer 270 Bar to my 300Bar O2 tanks. For the ability to pump 30-50 bar more into them having a booster is too expensive.
If the highest pressure I could get O2 from the supplier was 2400psi I would certainly have a booster, set to stall out just below 5000psi.

Where do you dive. That happens everyday in cave country. I’m shocked you dive in cave country and haven’t had an oxygen bottle filled to 33-3500.

I don’t know if any supplier in the US supplies high pressure oxygen above 2240. I’ve never asked since I’ve never seen it. If we could get 300bar oxygen I wouldn’t have a booster either.

He didn't say he planned to boost all the way to 3500 psi. Just because it can, doesn't mean it should.

I generally boost to 3300. My boosters cutoff is set to 3800.

Theres a cc shop that has been putting 3800 in my rebreather bottles lately. I suspect its more the employee not paying great attention

I started off in Cave country.... Currently in Nashville. I can understand boosting Nitrox blends up to 3500... but pure o2 to even 3000 seems a little crazy to me.

It seems everybody has different levels of oxygen comfort. I'm completely comfortable up to 3500. I personally won't go up to 3800 at home, but don't care if a shop boosts to 3800. It's not going to spontaneously explode unless dropped and we're careful. Not to say it couldn't happen. But we're cave diving, it's a high risk sport. Throwing a little hp oxygen in the mix isn't going to worry much more.
