Not too entirely clear on your question. Are you wanting to buy a filling system?
Lots of shops simply bank large tanks full of EAN32 and EAN36. I preffer a shop that will blend whatever mix you want to suit the diving you will be doing(assuming its under your training experience).
I hope that answers atleast a portion of your question.

I'm pretty sure there's no such thing as DNAx.
You should learn about the various methods (banked, partial pressure) of creating Nitrox in your class.
EANx stands for "Enriched Air Nitrox of x%." For example, EAN32 is nitrox with 32% oxygen.

Whether you remove nitrogen or add oxygen, regardless, you get the same air fill. Example, if you want a 32% fill, you set it up for 42% whether you use either method.
Perhaps you were asking what the advantages of Nitrox was over "regular air".
Basically, diving Nitrox lowered your nitrogen levels in your body which increased your "No Decompression Limits" which means you get longer dive times. You still
use your air/gas consumption at the same rate regardless of what you breath.
Some will say though that diving Nitrox will not make you as tired as you are
breathing more oxygen into your body. I am one of those who also agree
with this. I'm not as tired after I dive nitrox.
The real advantage of Nitrox is if you're doing deeper dives (over 60 feet) and
doing repetitive diving, like you would on a Liveaboard where you might easily
do 4 to 6 (or more) dives per day. Nitrox keeps your nitrogen levels down
which in turn increased your NDL for these repetitive dives.
One last benifit about the Nitrox class is that if you feel you didn't spend
enough time on your dive tables in your open water class, then it's a great
class for tables because you work them a lot in this class.
hope all that helps.

Gotcha.
Its just another way to Partial Pressure Blend. They basically filter nitrogen out of the gas through a membrane, leaving oxygen to get a desired oxygen content. I really don't know which is better - I'm sure both work fine. Our shop has a membrane, but doesn't use it. They blend the gas in the tanks by adding the gasses seperately.

As a diver rather than a nitrox supplier, it doesn't matter much. The end result is the same mix.Xpress:
The only advantage to DNAx or membrane systems is that you can fill tanks that haven't been O2 cleaned.
With the partial pressure method of blending nitrox, 100% O2 is used with air to get the right O2 content. SInce 100% O2 is used, the tanks needs to be O2 cleaned.

ya know, I've never seen anything on a tank that says whether it was o2 cleaned or not. You'd figure that the 'partial blenders' would want to know this before they dumped pure 100% o2 into a tank.
is there any system for this?
