How is zeolite used in oxygen concentrator systems?

In oxygen concentrator systems, zeolite is used as the primary adsorbent material in a process called Pressure Swing Adsorption (PSA). When air is compressed and passed through zeolite beds, nitrogen molecules are captured, and oxygen is allowed to flow through. Once the zeolite becomes saturated with nitrogen, the system depressurizes, and the nitrogen is released, allowing the zeolite to regenerate and continue the cycle.
