(We can get several more Rix units with this kind = of >pricing if anybody is interested) I own a RIX SA6 and a Haskel pump. Don=B9t try to use the compressor = for this purpose. First, it will heat up more than desired and burn up the = rings much faster. Those things are bitchy enough to rebuild and you don=B9t = want to do it more than you need to. I use the Haskel for O2 only and it=B9s O2 clean. As I=B9m using a = rebreather I want full O2 fills (3000-3300 psi) and I cascade my He from 4 storage = tanks. I seldom lose any significant amount of He - even when I was doing open = circuit trimix - this way. If I do get down to the last few hundred psi of the He I = can transfer using the Haskell.
