I have run pure helium, 10/70, 15/50, 18/45, 32/30, and 50/50 through a Rix for bottom mix and deco gases. I have run the same gases, minus the 50/50, through a Bauer compressor as well. None of this caused any issues.....BUT....these compressors were impeccably maintained and I knew their maintenance history. Without having known their maintenance history, I would not run anything richer than 21% oxygen through. Pure helium is not an issue as long as you monitor the temps. The compressor WILL get much hotter than if you are pumping air, and it depends on the specific model whether or not it can handle those temps or if YOU need to keep an eye on it and let it cool when it gets to a certain point.
