OK, I hope I dont get beat up for this but Im getting set up to fill my own cylinders.. I have the big MC1A compressor and yes I will be sending off for an air test. I have no doubt I can easily produce breathing quality air but I would also like to produce O2 compatible air and blend my own nitrox. This is where it gets shady for me. Everything seems to be greatly exaggerated for extreme safety but I would like some real world answers.. just how clean does the air have to be and stay safe? Going by the tables you can breathe air with 20ppm oil particles 15,10ppm hydrocarbons water and so on.. but for O2 it drops to an amazingly clean 0.5ppm! Is the main danger the risk of explosion while filling or is it also harmful to breathe EANx mixed with "normal" breathing quality air?? I mean other than the nearly 100% O2 present in the cylinder during filling after mixed the typical solution is only 11% more O2 than plain air.
