As the inventor of the low-pressure oil-free medical molecular sieve oxygen generation system, Lianbang Medical's VPSA oxygen generation technology has undergone 16 years of iteration. Integrating low-pressure adsorption, vacuum desorption and oil-free design, it has obvious advantages over traditional oxygen generation technologies and is widely used in medical care and plateau environments, recognized by over 2,000 large and medium-sized customers including West China Hospital and Nanjing Drum Tower Hospital.
I. Core Process Innovation, Significant Energy Saving
Different from traditional high-pressure PSA oxygen generation, Lianbang's VPSA adopts "low-pressure adsorption and vacuum desorption", which only needs a blower to provide slightly above-atmospheric airflow, greatly reducing energy consumption. Vacuum desorption improves molecular sieve utilization and oxygen recovery. It saves over 40% energy compared with traditional high-pressure oil-containing equipment, cutting annual costs by 1/3. The fully oil-free design further enhances energy efficiency by avoiding pressure loss from oil filtration.
II. High Reliability and Longer Service Life
The oil-free design eliminates oil pollution to molecular sieves, while low-pressure adsorption reduces internal pressure fluctuation and component wear, delaying molecular sieve aging. Its innovative single-tower oxygen generation simplifies structure, reduces multi-tower switching failures, and ensures reliable long-term continuous operation.
III. Convenient Maintenance and Controllable Costs
The single-tower design reduces installation difficulty, floor space and costs. The intelligent PLC control system enables automatic operation with simple startup, lowering manual costs. The oil-free design reduces wearing part replacements and downtime. The remote operation and maintenance system realizes real-time monitoring and fault early warning, improving efficiency and avoiding oxygen supply interruption.
IV. Stable Oxygen Concentration for Diverse Scenarios
Adopting high-efficiency lithium-based molecular sieves, Lianbang's VPSA stably produces 90%~94% pure oxygen with small concentration fluctuation, meeting strict needs of medical and plateau scenarios. It has five product series to provide customized solutions covering medical care, plateau, family and health management [1][5].
V. Significant Technical Barriers and Industry Leadership
As a pioneer with national invention patents, Lianbang has formed unique technical barriers. From 2008 to 2024, it continuously optimized technology to solve traditional pain points. Its business covers over 30 Chinese cities, serving 2,000+ customers and becoming a benchmark in the oxygen generation industry.
