Product Details
PSA Oxygen Generator is a small-scale oxygen supply device based on pressure swing adsorption technology. It separates oxygen from air through medical-grade molecular sieves, featuring core advantages of compact size, fast startup, stable purity, and simple operation. As a mainstream model of psa medical oxygen plant, the 10L/min flow rate and 93% purity can accurately match the oxygen supply needs of outpatient clinics, emergency departments, and small wards in community hospitals. It does not rely on bottled oxygen and can provide continuous oxygen supply by simply plugging into a power source, significantly reducing the oxygen supply costs and management pressure of hospitals, and serving as an ideal oxygen supply solution for community medical scenarios.

As grass-roots medical hubs, community hospitals have daily oxygen demand concentrated in outpatient emergency care (e.g., myocardial infarction, respiratory failure), chronic disease management (e.g., COPD), and auxiliary oxygen supply for small-scale surgeries. The single oxygen flow rate is usually 3-8L/min, and the daily oxygen use duration is about 8-12 hours. Traditional bottled oxygen has three major pain points: first, high labor costs due to frequent cylinder replacement (50-100 cylinders need to be transported by special personnel monthly); second, storage risks (high-pressure cylinders are dangerous goods and require a separate warehouse); third, cost fluctuations (the price of bottled oxygen is affected by transportation and seasons, with an average annual cost of about 20,000-30,000 RMB).
The 10L/min flow rate of the PSA Oxygen Generator can support 3-4 oxygen inhalation terminals simultaneously. Its 93% medical-grade purity fully complies with the national standard "Medical Oxygen" (GB 8982-2014), meeting the daily oxygen supply needs of community hospitals. Its psa system for oxygen technology requires no chemical raw materials and produces oxygen directly from air, with an operating cost only 1/5 of that of bottled oxygen (about 3-5 RMB in electricity fees per day), saving more than 20,000 RMB annually. In addition, the equipment covers an area of only 0.2㎡ and can be directly placed in the nurse station or treatment room without the need for a separate warehouse, greatly simplifying the management process.
PSA Oxygen Generators in community hospitals need to maintain high stability, and scientific maintenance can extend their service life to more than 5 years.
- Before daily operation: Check if the air intake filter is clean (rinse with clean water once a week and replace once a month) to avoid dust blockage affecting oxygen purity; replace the water in the humidifier bottle daily and disinfect it with alcohol weekly to prevent bacterial growth.
- Monthly maintenance: Test the oxygen purity with a portable oxygen concentration detector. If the purity is lower than 85%, the molecular sieve may be damp or aging – contact the manufacturer for regeneration or replacement (normal service life is 2-3 years); as a core component, the compressor requires inspection of the cooling fan every six months to remove dust and ensure good heat dissipation.
- For long-term idleness (e.g., holidays): Start the equipment to run for 30 minutes every week to prevent the molecular sieve from dampness and failure.
It is recommended to establish a maintenance log, where nurses or equipment managers regularly record the operating status. If abnormalities are found (e.g., increased noise, decreased purity), contact after-sales service in a timely manner to avoid downtime caused by minor faults.
With its precise 10L/min flow rate and stable 93% purity, the PSA Oxygen Generator has become an efficient oxygen supply choice for community hospitals. Its psa medical oxygen generator technology can not only meet the oxygen supply needs of grass-roots medical care but also reduce the burden on hospitals through low-cost operation. Combined with standardized procurement and maintenance, it can serve as a reliable guarantee for community medical services.
