Re: Easa approved

Commonly available in the USA .
OXYGEN, Research Grade 5.0 - Minimum Purity 99.999% - H2O <0.5 ppm
OXYGEN, Ultra Pure Carrier Grade 4.6 - Minimum Purity 99.996% - H2O < 1.0 ppm
OXYGEN, UHP Grade 4.0 - Minimum Purity 99.994% - H2O < 2.0
OXYGEN, Zero Grade 2.8 - Minimum Purity 99.8% -
OXYGEN, Aviators Breathing Grade 2.5 - Minimum Purity 99.5%
OXYGEN, Medical U.S.P. Grade 2.5 Minimum Purity 99.5%
OXYGEN, Commercial Grade 2.0 Minimum Purity 99%
Aviation oxygen should be IAW MIL Spec MIL-O-27210

In the USA ;- Further Ref. sources USP for US analytical standards, US DOT for classification, US CGA for grading information, US FDA Medical Gases Guidelines. It's similar in other parts of the world.

and check out http://www.scienceblog.com/community/older/archives/M/1/fda0622.htm

"In the USA as long as the oxygen gas is USP it may be used for mixing all sorts of concentrations of oxygen containing 'breathing mixes'. However, the transfilling of 100% oxygen into cylinders intended for medical or emergency-only cylinders requires that the FDA license the transfilling station." This has insurance and legislative implications.

And finally - from me anyway - some industrial applications need O2 that is purer than the stuff we breath...
 
Re: Easa approved

I'm a PADI dive instructor. Scuba tanks are filled with filtered air not O2. There are some mixed gas , but they are for special uses. O2 is toxic at depth. The compressors used for this are a designed to be oil free.
 
Re: Easa approved

The EASA Hot Shot approval only covers the turbo-normalizer convertion of 112. I beleive the turbo-normalizer convertion of 114 already exists with EASA. But I don't know for sure.

Regarding a flyin to Norway and perhaps Ørland. That is something to look into for the spring.

Re: Easa approved

For what this is worth.

I sat down with the manager at the Air Products depot and talked to him about aviator oxygen.

He explained that years ago they made the oxygen in batches and aviator oxygen was carefully tested. Now all batches are tested so they just group industrial, medical and aviation together. It is all of the highest standard.

He said that no moisture is added to medical oxygen, It is all the same.

I have purchased medical bottles off ebay very cheap and then Air Products will hydrotest the bottle and change the fitting to aviation from medical for $24.00 (and fill it)

Great deal.

Re: Easa approved

Thx Ken. We've been trying to spread that very info but some just refuse to accept what has become a simple (and expensive) "marketing" differentiation. Oh, well...

Many asked about you at this year's fly-in. You and your wonderfully droll sense of humor were missed.
 
Re: Easa approved

A word of warning for the oxygen suckers,

I asked to have a bottle filled at Las Vegas Henderson, ten minutes later they returned my bottle. Only to find out months later that it had been exchanged for one of theirs, and it was out of date.
I now have my company stickers all over them.

For the tight wads, I have the large oxygen cylinder in the hangar and transfer to the aviation bottles, when the large bottle is down to 1500 psi I take it to work and get a full one. I own the bottle so no monthy lease.

Missed Sedona this year, just too much work with the day job. Sounds like all had a great time.

Life is a barrel of fun.

Ken
