0.5-5L White Household Oxygen Concentrator With Purity Of 93±3% For Acute Respiratory Distress Syndrome (ARDS) Therapy

Product Parameter

Working Principle Description

Our home oxygen concentrator is the medical PSA molecular sieve oxygen generator.

The concentrator takes clean compressed air as raw material and uses high efficiency lithium molecular sieve as adsorbent to produce oxygen from air under certain pressure.

The compressed air after purified and dried , were carried out in the adsorber by pressuring adsorption and decompression desorption. Due to the aerodynamic effect, the diffusion rate of nitrogen in the pores of lithium molecular sieve is much higher than that of oxygen. Nitrogen is preferentially adsorbed by lithium molecular sieve, and oxygen is enriched in the gas phase to form finished oxygen.

Then, the adsorbent desorbs the adsorbed impurities, such as nitrogen, to achieve regeneration after decompression to atmospheric pressure. Generally, two adsorption towers are set in the system, one is for adsorption and oxygen generation, the other is for desorption and regeneration.

PLC program controller is used to control the opening and closing of pneumatic valve to make the two towers circulate alternately, so as to obtain higher purity oxygen (93%±3).
