The Trident Oxygen Generator works on the **principle of Pressure Swing Adsorption (PSA)** to produce oxygen from atmospheric air. Ambient air is first filtered and compressed, then passed through vessels filled with a special adsorbent called zeolite. The zeolite selectively adsorbs nitrogen molecules under pressure, allowing oxygen to pass through as the product gas. When the vessel becomes saturated with nitrogen, the pressure is released, and the adsorbed nitrogen is expelled, regenerating the zeolite. By cycling between two vessels, the system continuously supplies high-purity oxygen for medical or industrial applications.
