9l at 137bar is 137x9l so you get 1223l of gas expanded, or 123.3 minutes at 10lpm, though boc and some others list the cubic feet or meters in their cylinders to start with.
edit, not the same with co2, that is stored as liquide and remains at about the same pressure no matter how much is in the tank i believe, i've never used big tanks of co2.
i've gotta find somewhere that does these 20l at 200bar i think... i've got adams gas 9l at 137bar on my mig at the moment, i had one on my tig but it was really expensive on fills, so i've got a 6ft tall boc cylinder on that now![]()
really GC motor factors? thats interesting, do you have a price list? any suppliers in cardigan? i see you do oxygen to, thats very interesting![]()
