How PSA Oxygen Concentrators Working?

PSA Oxygen Concentrators Working Principle

 

Air enters the compressor after filtered by the air inlet filter and is compressed into molecular sieve tower for separation of oxygen gas and nitrogen gas. Then, oxygen gas passes through the molecular sieve tower and enters the fine sieve tower smoothly, while nitrogen gas is discharged into the atmosphere through the separating valve after adsorbed by the molecular sieve. After the concentration of oxygen gas is further increased in the fine sieve tower, the flow rate is controlled by the flow control valve, and then oxygen gas is wet through the humidification water tank and

finally flows through the oxygen delivery pipe for supplementary oxygen inhalation by users.
