How does an oxygen concentrator zeolite system function?

An oxygen concentrator’s zeolite system functions by using pressure swing adsorption (PSA) technology to separate nitrogen from ambient air. Air is drawn into the concentrator, compressed, and then passed through zeolite beds. The porous structure of zeolite selectively adsorbs nitrogen molecules due to their size and polarity, allowing oxygen molecules to pass through. The oxygen-rich air is then delivered to the user, while nitrogen is trapped. Once the zeolite becomes saturated with nitrogen, the pressure is reduced, allowing the nitrogen to be released, and the zeolite is ready for another cycle of adsorption.
