Do you have to have seperate tanks for Nitrox and regular compressed air? can they be swapped out pretty easily? Im guessing it makes no difference at all but just want to be sure
Below 40% Nitrox, you can dive with regular tanks that are marked for use with Nitrox, unless the fill station uses partial pressure blending. If they use partial pressure blending, then the cylinder could be in contact with pure oxygen, requiring it to meet oxygen service standards.
There is also a special green and yellow band that goes on the tank. Above 40% O2, you always need an O2 clean tank that is rated for Oxygen service. This is not your standard run-of-the-mill Aluminum 80 that you find at the LDS.
