Dr. Sumait established a medical PSA oxygen generator system consists of the air compressor, air-water separation device, dryer, air dew point monitoring device, multi-stage filter, air buffer tank, air moisture monitoring device, oxygen generator, oxygen buffer tank, flow meter, online oxygen monitoring device, cylinder manifold system, smart electric control cabinet, computer monitoring system, remote network monitoring system and oxygen booster system.

The medical molecular sieve PSA oxygen generator system adopts the international advanced pressure swing adsorption (PSA) technology to form a rapid cycle of pressurization adsorption and depressurization desorption under the conditions of average temperature and low pressure. When the adsorption capacitates of the molecular sieve for nitrogen in the air increase during pressurization (and vice versa), oxygen and nitrogen are separated from the air to generate oxygen, with air as the raw material and zeolite molecular sieve as the adsorbent.
