As long as there's an FAR about Aviator's Breathing Oxygen.Â* Oh, wait...

There is absolutely NO DIFFERENCE between medical, aviators or welding oxygen. Moisture may be introduced at the delivery device for medical applications, but in the cylinder itself, they are all 99.99% O2. Any moisture in the pressurized cylinder, in the presence of an oxidizer (O2, get it?) promotes corrosion of the aluminum or steel cylinder. I wonder how long this fairy tale about the "differences" in oxygen will survive? -- Dan, 5J |

ABO is tested for moisture on an individual cylinder basis. Medical O2 is tested for purity on a sample basis (usually one cylinder out of a 20 cylinder line). Industrial O2: each cylinder is sniff tested prior to filling to make sure no flammable gas or other stinky thing is loitering in the cylinder. No testing of industrial grade after filling.
Yes, all are filled from the same liquid O2 tank, all are pumped on the same manifold. However, the compliant filling facility does the above steps because either FAA, FDA, or CGA says that is how to do it. It's reasonably easy to play safe: have a CGA 540 tank, get a fill from an ABO cascade manifold at the airport. It is not reasonably easy to get a "great price", especially if you fly where there is no ABO manifold available.. |

Ask anyone who has ever done a decent physics class what happens to moisture when you compress a wet gas. It drops out. That’s why air compressors have moisture traps.
This nonsense about testing for moisture/adding moisture in medical oxygen etc etc never goes away. Compressed oxygen is incredibly dry. Any moisture in a compressed oxygen cylinder would be rolling around the bottom, not in the gas. |
