A system for oxygen enrichment of fresh air is used as a module in the environmental control system of aircraft cabins. Due to the increased oxygen partial pressure, the total air pressure in the aircraft cabin may be reduced, thus leading to increased cost economies in design and/or operation. The module provides oxygen-enriched fresh and recirculated air that is free of any particulate and gaseous pollutants, especially ozone and carbon dioxide.
