The invention provides a system for oxygen enrichment of fresh air, which is used as a module in the environmental control system of aircraft cabins. As a result of the increased oxygen partial pressure the total air pressure in the aircraft cabin can be reduced, thus leading the increased cost economics in design and/or ownership. The module as per full patent claims provides oxygen - enriched fresh and re-circulated air which is free of any particulate and gaseous pollutants, especially ozone and carbon dioxide.
