I?m interested in building my own home oxygen transfix system but would like to talk to someone who is doing it. Please pm me or email at rightseat@ Gmail.com
Thanks

On a related note, I purchased a used Inogen G2 portable oxygen concentrator locally off craigslist for something like $1k including 3 batteries. A machine not to refill tanks but rather to produce concentrated oxygen on-the-fly (as it were).
I've only used solo at a max altitude of 15k but the machine kept up. Google says weight is 7.25 pounds with one battery (can run off 12v). Very compact and convenient.
Do you use a pulse-oximeter? I'd be curious what levels you were able to maintain at altitude.
seems that i remember from the 60's when i got a diver's card that using compressed air that wasn't delivered by a pump for air meant to be breathed could be dangerous because the wrong type of pump could also deliver oil into the compressed gas.
I recently joined a group that shares a refill tank. The three tank setup helps ensure you get as much out of each tank as possible and can top off the airplane tank. We are looking for a third tank.
We have a six tank group at the airpark - we split the cost of the daisy chain charging rig. It costs $40 to exchange a tank for a full one. My one tank investment has provided a half dozen refills of my rather large Mountain High AL-682 tank.

Great thread since I want to build my own system. As far as refilling from a large tank and getting a full fill as the source tank empties, has anyone used a small high pressure booster pump till the source tank is empty. I found very small pumps available from scientific supply houses that are oil free and seem like they could do the job. And what?s the ideal size of tank to use in a RV that will last a reasonable time?

houses but their not very clear on the lubricant used in the unit. Any oils near pure oxygen are extremely unstable and self igniting. I remember very vividly a training film I saw years ago showing what happens when you just put oil on a oxygen regulator fitting to make it thread on easier. Nasty explosion. Cleanliness is of the upmost importance around oxygen.
Having never filled one before I?m glad my buddy had. Even going slowly it produces a lot of heat to the filling tank!
Can you elaborate on this 15-20 minutes? I am aware of the concerns with "popping" or quickly opening a bottle, regulator failure, etc. But once everything's stable, I was not aware of any flow rate limitations on oxygen when transfilling.Cylinder should not get too warm and definitely not too warm to hold comfortably. When we fill 2L O2 cylinders for diving it takes around 15-20 min to keep the flow rate safe.

Refills at the medical store are $18. That is 6 hours of O2 use for my wife and I..
Will most medical supply places refill tanks for non medical (no script) use?
Not sure on medical supply places, but most bulk gas supplier will happily fill your bottle with Aviator Grade O2 with no script.
My industrial gas supplier fills my medical O2 bottles with either a prescription or a pilot's license as proof of need. Got to have one or the other...
