Medical PSA Oxygen Generator with 99.5% Oxygen Purity

The core of this PSA oxygen generator uses high-quality molecular sieve as the adsorption medium. Under the working principle of pressure adsorption and pressure desorption, the system efficiently separates oxygen from compressed air. Nitrogen, water vapor and carbon dioxide in the air are adsorbed by molecular sieves, while high-purity oxygen is separated and output steadily. Our optimized air circuit and control algorithm guarantee that the oxygen purity can stably reach 99.5% under rated working conditions, meeting strict medical oxygen application standards. The selected molecular sieve features high nitrogen adsorption capacity, excellent anti-powdering performance and long service life. It can withstand frequent cyclic pressure changes inside the tower, maintaining consistent separation performance for years without rapid performance degradation. Before entering the adsorption towers, raw air passes through a multi-stage pretreatment system, including air filter, refrigerated dryer and oil removal filter, to remove oil mist, dust and moisture, protecting the molecular sieve from contamination and extending the service life of core components.
Compared with traditional oxygen supply modes, on-site PSA oxygen production brings remarkable advantages. Cylinders and liquid oxygen tanks require complicated transportation, storage and regular replacement, which may cause oxygen supply interruption in emergencies. Liquid oxygen also requires strict cryogenic storage management and periodic safety inspection, while oxygen cylinders carry risks of handling damage, leakage and high delivery costs, especially for remote hospitals and medical stations with poor logistics access. Our on-site PSA unit produces oxygen on demand 24/7. Once installed, it can run continuously, greatly cutting long-term operating expenses and eliminating recurring procurement fees for cylinder refilling or liquid oxygen delivery. The fully automatic control system supports unattended operation. Operators can check real-time oxygen purity, pressure, flow rate and equipment running status through the touch screen. Alarms will be triggered automatically for abnormal pressure, low oxygen concentration or system faults to ensure safe operation. All alarm records and historical operation data can be stored and exported for medical facility record auditing, which satisfies hospital quality control and inspection requirements.
This 99.5% high-purity medical PSA oxygen generator is widely applicable to multiple medical departments: general wards, emergency rooms, operating rooms, intensive care units (ICU), neonatal wards, respiratory departments and hyperbaric oxygen chamber supporting oxygen supply. It can also serve large medical projects, rural medical centers and field medical stations. We customize different flow models according to customer demands, to match oxygen consumption of small clinics and large general hospitals. The equipment can work independently or be connected in parallel for capacity expansion, which offers great flexibility when hospitals plan to expand wards or upgrade oxygen consumption capacity in later phases. The outlet oxygen pipeline can be connected directly to the hospital central oxygen supply pipeline network to realize centralized oxygen supply for the whole medical building.
The whole machine strictly follows medical device quality management standards, with complete testing reports and supporting certification documents. Every unit undergoes strict factory performance testing before shipment, including continuous load running test, purity stability test, pressure test and safety alarm function verification. We provide one-stop services including scheme design, production, factory testing, on-site installation guidance, commissioning, staff training and after-sales maintenance. Our professional engineering team can also assist customers with layout planning of the oxygen station, pipeline design and ventilation safety design of the equipment room. Our company has rich experience in overseas medical engineering projects, such as the hospital project in Tbong Khmum Province, Cambodia, where we delivered PSA oxygen equipment and medical clean renovation works. We fully understand overseas hospital construction specifications, cross-border delivery requirements and local medical project acceptance standards.
