This medical-grade stationary oxygen concentrator is an electronically operated device engineered to provide a continuous, high-purity stream of supplemental oxygen directly extracted from environmental ambient air. Operating on standard alternating current (AC) power, this device eliminates the logistical constraints of exhaustible compressed gas cylinders by utilizing an advanced structural framework to continuously separate and concentrate atmospheric gases at the point of care.
The core pneumatic architecture relies on an oil-free internal compressor coupled with a dual-bed Pressure Swing Adsorption (PSA) system. Ambient air is drawn through a multi-stage filtration assembly to remove gross particulate matter and airborne contaminants before entering the pressurized sieve beds. These beds contain a high-grade crystalline zeolite molecular sieve, a specialized mineral material that preferentially adsorbs nitrogen under pressure while allowing purified oxygen to pass through into a centralized storage tank. The system dynamically alternates pressure between the twin beds, venting trapped nitrogen back into the environment during depressurization to maintain an uninterrupted operational cycle.
