IV. Working Principle 

Air is compressed by an oil-free air compressor, and the compressed air flows to the inlet P of the rotary valve, which is controlled by the control panel.

 

1. When the rotary valve is energized, the compressed air flows from P to A, then from the A port of the rotary valve to the molecular sieve (A bed). The nitrogen in the compressed air is adsorbed by the molecular sieve, while oxygen enters the flow meter to control the output flow for oxygen use.  Another path enters the molecular sieve (B bed) through the desorption port for washing and desorption, and the desorbed gas is discharged to the atmosphere through the exhaust silencer of the rotary valve.

 

2. When the rotary valve loses power, the compressed air flows from P to B, then from the B port of the rotary valve to the molecular sieve (B bed). The nitrogen in the compressed air is adsorbed by the molecular sieve, while oxygen enters the flow meter to control the flow for oxygen use. Another path enters the molecular sieve (A bed) through the desorption port for washing and desorption, and the desorbed mixed gas is discharged to the atmosphere through the exhaust silencer of the rotary valve.

 

After this working cycle ends, the rotary valve is controlled again, entering the program for A. This process continuously adsorbs nitrogen and collects oxygen, enabling the two beds (A and B) to work alternately, thereby producing oxygen directly from the air and providing a continuous supply of oxygen for use.
