O2 clean tank + Air
Hi

my friend at work has 2 new 12l 300 bar steel tanks. where we are , nitrox isnt always available and on a planned weekend livaboard its deffo not available.

the question is, can the tanks be charged with normal breathing air via the boats onboard compressor and will this cause the O2 clean status to be void.

if they can be filled without the 02 clean void, are there compressor or minimum filtration details someone can let me have so i can check with the charter Co. ?

thanks

D

I'd suggest asking the boat provider if they can provide clean air for Nitrox cylinders. They ought to know really...

It depends...

"Clean" air is double-filtered. Most places these days have clean air, but a boat might not.

Ask the skipper.

Here we go again. It depends on who you talk to. Some say Double filtered, others mention EN12021, whilst others argue against EN12021 being a minimum standard that only mentions 21/22% O2, and that 'Use No Old' still stands.

I don't pretend to have all the answers but I would not argue for one thing or the other publicly without having backup.
