STEP I: - In the first molecular bed, compressed air is fed in which nitrogen is trapped and oxygen flows out.
STEP II: - When the first bed is filled with nitrogen, air flows into the second bed.
STEP III: - When the second bed separates oxygen from nitrogen, nitrogen is vented out in the atmosphere in the first bed.
STEP IV: - Again the compressed air flow in to the first bed, the process continues and there is a constant flow of oxygen.
