The Nitrogen gas generator works on principle of separation of air into Nitrogen and Oxygen.
PSA (Pressure swing adsorption) technology separates nitrogen molecules from the other gas molecules by the carbon molecular sieves (CMS). Alternating between both CMS columns, firstly O2 , moisture, hydrocarbons, CO2, and other “contaminants” are absorbed, allowing the nitrogen to flow into an accumulation tank. From the accumulation tank the nitrogen is pressurized and delivered to the generator outlet for use.
