My understanding is that medical O2 is specifically supposed NOT to be dry....

Years ago a friend of mine was CEO of the then CIG and we were worried and run a test on moisture on medical cyclinder and it easily meet the aviation std. This is not the advice I received from BOC (they could not guarantee it was dry) - nor my experience. As noted in a previous post, I have had one occurrence of freezing up of the valve during a transfilling operation, which suggests that there is some water present in medical O2 on occasions. -- Regards, ----------------. .---------------- ---------- \ __ / ---------- -------- \(..)/ -------- ----- ;\/; ----- ---- : : ---- --: :-- //..\\ VV VV '//||\\` ''`` Peregrine!
