The working mechanism of this oxygen concentrator is based on Pressure Swing Adsorption (PSA) technology. This advanced method allows the device to separate oxygen from nitrogen in the surrounding air. Once air is drawn into the machine, it passes through a series of filters that remove dust, allergens, and impurities. The nitrogen is then absorbed, while purified oxygen is collected and delivered to the patient through a nasal cannula or mask.
This continuous cycle ensures a stable oxygen concentration level, typically around 90–96%, depending on usage conditions. The machine is designed for long-term operation and includes built-in safety features such as alarms for low oxygen purity, power failure, or pressure fluctuations.
