Every time you post I feel better about buying a Rix. In the same way I feel great about buying a Toyota when I'm at the dealership. You feed my fanboy reverence for the product. I have however seen you make some references to not pumping nitrox through a rix. What is the reason for that?
And every time you post about what your doing with the thing I loose sleep LOL
Three clear and concise reasons for not pumping nitrox with a SA-6. (without a clear understanding of the build spec and the modifications required)
1. First read the Data Plate, the label will tell you what gas it is designed for. Or on the registration page in the manual.
2. If the model number starts with a SA-6 or SA-6A or SA-6B and it say air compressor, it is an air compressor.
3. Don't use the generic company name Rix and not include the critical model number.
The fact that the SA-Series are oil-free and both oil-free and oil-less air compressor is an advantage granted but none the less it is still an air compressor unless built otherwise.
Now by contrast say you want a 30 CFM or 40 CFM 5000 psi compressor for compressing Nitrox up to lets say 50% or 60% or 70% I don't care. The model number would be the same, but lets say you now required it suitable for compressing pure 100% oxygen filling to say 3625 psi, with say upto a 5psi inlet pressure, then the model number would be different again.
The only other interesting issue you are going to struggle with is that both the compressors above for nitrox or oxygen are oil lubricated and use 7 litres of standard mineral based oil for lubrication, not only is the oil standard mineral based machine oil costing about $20 a gallon and with a standard $15 automotive type oil filer.
But the $20 oil change is every 5000 hours running (Five Thousand hours)
Funny old world. But I trust you see the difficulty in making generic statements.
