    possible o2 sources

aviation grade any good air port that services large ga aircraft.

most nitox diving shops but your fittings have to scuba types

or medical o2 supplier but you need a scrip to get o2 from them.

you can get o2 from you industrial gas supplier in breathing grades but they normal only supply it in large tanks. and you would have to set up a cascade system for your fills.

Thank you all for your info,

 

Dan, if you were to use medical O2 cylinders would you have trouble having them refilled?

 

Here in the UK if you want medical grade O2 you need to be registered as doctor or pharmacist, it is treated as a medicine. However if you want ?diving grade? oxygen it is easer to purchase. From what I can gather diving grade would be better for us anyway as it is ?drier? than medical grade. This will help keep the humidity down in the sub.

 

?Industrial Oxygen? is the cheapest but is not recommended for breathing, I presume this is because it is not pure.
