ABSTRACT:
A method of supplying oxygen rich air to the passengers and crew on board a passenger aircraft by use of a highly permeable oxygen enrichment unit, wherein the fiber tubes of the hollow fiber membranes used to separate normal air into oxygen rich and nitrogen rich fractions in the oxygen enrichment unit are subjected to a modification technique before the tubes are coated with a selective polymer.
