hi, yes i certified as a gas blender..... this is the scuba side of things... as we all know... the science side differs quite as much.. secondly... oxygen cleaning is another course.... which i have yet to take... but would like to ask in advance since im already making nitrox I still need...

ok i just checked oca

what do you mean pumping OCA? No cleaning? well.... just wana be thorough... or be sure.... that the last person who installed the valve could have used silicon grease on the neck o ring....

im approximately at 36 bottles per change. at 12 hrs. as some bottles have 40bars. but some has leftovers of 90-110bar.... I have kids and wife diving.... they dont seem to breath :p much

hi this is what i was clarifying... i had new valves installed on some tanks. and now im getting into Nitrox blending. for the record i certified for that. so ..... im there using those same valves and tanks. rated 40% nitrox. 6months old. being filled only with air by my own compressor...

heheheh i had 2 not oxygen cleaned deco regs. 1 was for 50% nitrox and the other 100%. i oxygen cleaned it after a few dives… but take note did a few dives with it while being not oxygen cleaned. Just opened it really slow with purge pressed.

So what are we doing oxygen cleaning our valves for pp blending?

Thanks this is what i meant… any nitrox ready valves can be oxygen cleaned without replacing the existing bnew viton orings by just degreasing everything then using oxygen compliant grease

so... Z5?

ah yes.. im aware of this.. but in the absence of a "green colored" valve for oxygen..
