    Hello,

    Quick question on reg cleaning for recreational Nitrox use. I've had these regs for just about a 10 months and have about 12-15 dives on them using only air. Don't know if all that air was "clean" air since much of it came from a couple of different local quarries' compressors with the balance coming from a Ft. Lauderdale dive boat's tanks. Do I need to have them O2 cleaned and if I do, will use of air from the same compressors void their O2 rating?

    Thanks,

    Mike

    If you're using Nitrox mixes below 40%, there is no need to ever have your reg O2 clean. Regs only need to be O2 cleaned for higher O2 concentrations.

    you are safe with a recerational nitrox mix.

    This is right on BUT if the shop providing Nitrox fills uses partial pressure blending (100% 02 mixed with air in your tank) you will need the gear 02 cleaned. Many places (at least in my area) offer pre-mixed Nitrox so I do not need anything 02 cleaned for less than EAN40.

    Gear = tanks and valves?

    Yeah but that pure O2 never touches your reg. All that has to be cleaned for partial pressure blending is the tank and the valve. Your reg only 'feels' the mixed variety.

    Ha ha ha - yes of course - I totally blanked in my reply. My head is still numb from the cold water temps today (35 F). >40% everything must be 02 cleaned. <40% no worries except for tanks if getting pp fills.

    As long as mix is banked and less than 40%, you sre good to go.

    That only affects the tank(s) and not the regs.

    Spare us! Read above posts before replying please. He's talking about regs, they only touch the final blend of nitrox, not what goes in during PP blending.

    Not unless you deal with one certain shop that I know of. There they insist that you must have your regs O2 cleaned and serviced, unless you bought them from him. In which case they are good to go. He must get his gear from a different box.

    I'd not buy anything more than an air fill from that shop and only then if it was much more convenient than anyplace else. I'd also tell them why. I can be stubborn that way though.

    I wouldn't bring your regs into that shop when filling your tanks. If the idiot persists, ask him if he will O2 clean your BC. It's fun to watch morons squirm, but only in front of other people :eyebrow:

    Thanks to everyone for the quick and detailed replies. I do not own a tank mostly because everyone in my area that fills Nitrox uses PP blending and I don't want to dive Nitrox on every dive and don't get to dive enough to justify two separate tanks for both the wife and I.

    Thanks again for the help and wish us luck as we are taking the SSI Nitrox course in the next 2 weeks!

    Hey. If the regs need it then the BC surely would too. <g> BTW. What if you are diving a 50% mix? Would you need an additional bottle (like Argon for a drysuit) for the BC? Since you brought it up, how does that work? Is there not enough pressure in the BC system to be a problem?
