It may be the wrong thread to post in, but what's the deal with these things?
What do I need for it to fill my HPA tank, is the nitrogen tank what fills the HPA tanks?

Well highly pressured air and nitrogen are 2 different things. Highly pressured air is just regualr co2 with O2. Which is what we breathe. I dont know much about nitrogen. Contact rob from ninja. Hes all over the air systems section

You do know the air you breath is mostly nitrogen, right?

There is hardly any co2 in the air, less than 1% if i remember correctly.

So, high pressure Air is mostly nitrogen. However, you can get pure Nitrogen from certain shops. It's more expensive than compressed air but, it is suppose to run a little more efficiently.

Yep. I just looked in my dive book. It is nitrogen. Not Co2. My bad
