Design Specifications
FREO2 uses a “molecular sieve” to remove nitrogen and leaves mostly oxygen. FREO2 passes a small amount of flowing water through a siphon to produce a vacuum and mechanically converts part of this to compressed air. The vacuum and the compressed air power a vacuum pressure swing absorption system to concentrate oxygen.
