Oxygen Enriched Air (OEA or NITROX)

PRISM membrane separators use selective permeation to separate oxygen molecules from compressed air. The resulting low pressure stream of oxygen enriched air contains oxygen levels of approximately 25%-50%. Common OEA applications include underwater diving and high altitude enrichment as well as other industrial uses.

 Data Sheet


PRISM Membrane separators are used to inert airplane fuel tanks as part of the onboard inert gas generating systems (OBIGGS).
