Nitrogen generators and oxygen generators operate with principle APX INTERNATIONAL produce a constant flow of nitrogen or oxygen from compressed air filtration : remind that air is composed of 78% nitrogen, for 20.8% of oxygen the rest by traces of other gases (argon, helium, hydrogen…)

 The system is made up by two sets of aluminum extruded columns that are filled with “CMS” (carbon molecular sieves) to produce nitrogen or “zeolites to produce oxygen. These materials have physical features such as to permit a mechanical-holding of oxygen molecules for CMS  sieves or to hold nitrogen molecules for zeolites sieves. A stream of compressed and pre treated air crosses the columns from the bottom to the top. The oxygen or nitrogen is absorbed by the filtering material, whereas nitrogen or oxygen outgoing from the top of the towers is collected in a storage tank and ready to be used.
