You can reach Rix Industries at: RIX INDUSTRIES 4900 INDUSTRIAL BENICIA CA 94510 (707) 747-5900 (707) 747-9200 My last contact there was Rick Turnquist. Regarding getting the Rix machine so you won't have to change hyperfilter cartridges, this only helps a little. A conventional oil-lubricated compressor in the 5-9 scfm range will have a final separator (sinitered element type), and a single filter housing with a "combo" purifier cartridges. Then you would normally go through two more filter housings for the hyper-pure. Hyperpure cartridge, on a per fill basis will cost between 30 cents and 50 cents, depending on the filter system you get (this is in addition to the standard breathing air filter cartridges). It is a common belief that the Rix is run with no filtration. The machine is shipped that way, and the air is breathable that way, but it is quite damp. This causes problems in cold water diving and in steel tanks. Therefore, many suppliers add a coalescor (sinitered element mechanical separator) followed by either a dryer or combination purifier cartridge. While it is not necessary to add more filtration to remove trace contaminates, it is necessary to add a micron particle filter to catch any stray filter media from the "standard" cartridge. Then, you have oxygen compatible air. Continuous blending with the machine is pretty cool. It is really for a production sort of application, because unlike with partial pressure mixing, it is not practical to pump a bottle of air, then a bottle of EANx32, then a bottle of EANx36, etc. That is because any change in the oxygen injection system, takes several minutes to be seen at the compressor outlet. So, you want to set it up for a certain mix and fill a number of tanks or storage cylinders. Regarding the oxygen injection system, you can buy something like the Nitrox Stick, the IANTD quick gas, at hundreds of dollars, or you can get someone to build one for you at low cost. There is nothing magical about these oxygen injection systems, and many suppliers go out of their way to make them overly complicated (boy I'm going to get flamed now). The bottom line is, the Rix machine is very cool, and gives you some options that you can't get with an oil lubed machine. New cost, comparing apples and apples is competetive with oil lubed machines. I hope this information helps! Sincerely, C.
