The math isn’t complicated, the notion of someone banking 28% isIf a shop has EAN28 banked, then mixing 35% helium and 65% EAN28 will yield 18/35 (actually, FO2 = 18.2, FN2 = 46.8, and FHe = 0.35). Straightforward.

The neat thing about EAN28 is one can dive it (open circuit) to the recreational training depth limit of 130 ffw and NOT exceed a PO2 of 1.4 ATA.The math isn’t complicated, the notion of someone banking 28% is

I stand corrected... However... it is used as the first gas on your CCR1 class. Even if you are trained within GUE, if all you can get is air... then you can absolutely dive with air.This is maybe a GUE standard gas for suit gas and tires, but not for dil... ;-)
Not as a standard. We started with NX32, which imho is a very "bad" gas for a breather with 2 x 7L Dil bottles. With a rebreather you want to have your rig as balanced as possible. And 3.5kg of gas in this case are a pita...it is used as the first gas on your CCR1 class.
It's pretty useful in MX on CCR. It's not very deep for the general Tulum area caves and using nitrox helps avoid every tiny dil addition messing with your ppO2 and requiring an O2 addition to bump your fO2 back up.I have never seen a eanx for dilluent in Europe, probably because we don't bank nitrox that often.
In what case would a 32% dill be usefull?
