Most Manufacturers void the warranty for filling cascade systems or using Nitrox, What about AireTex?
AireTex does NOT void the warranty for using Cascade Systems or Nitrox in fact we sell many of those systems with our compressors. With that said if you are running your compressor 8 hours a day then you obviously need a larger compressor. The AireTex compressors are approved for Nitrox up to 40%.
