Home oxygen concentrators need to monitor a number of pressure values during daily use to ensure that they operate properly and provide a stable oxygen output. First of all, the working pressure is one of the key parameters of the oxygen concentrator, which is usually set between 0.04 and 0.07MPa to balance the effect of oxygen production and the stability of the equipment operation. Secondly, the oxygen outlet pressure is also an important indicator, usually between 40~100KPa, which may vary with different models of oxygen generators. Compressor power is another important factor, high power compressor can provide greater oxygen flow and higher pressure, especially in the use of highland areas. Finally, the adjustment of the molecular sieve adsorption time will also affect the performance of the oxygen generator. Reasonable adjustment can improve the oxygen production and stabilize the pressure.

Working Pressure
The working pressure of the home oxygen concentrator is one of the most important parameters to pay attention to when purchasing. Generally speaking, the working pressure of home oxygen concentrator is set between 0.04 and 0.07MPa. This range ensures both the effectiveness of oxygen production and the stable operation of the equipment.
Oxygen Outlet Pressure
The oxygen outlet pressure of a home oxygen concentrator is also an important indicator. Oxygen outlet pressure values for home oxygen concentrators are usually in the range of 40~100KPa, depending on the model. For example, desktop oxygen concentrators tend to be in the range of 40 to 60 KPa, while some specific models of diffusers can reach 100 KPa. These pressure values ensure that the oxygen is delivered steadily and continuously to meet the users needs.
Other Related Pressure Factors
Although the regulator valve of the oxygen generator can fix the pressure value, the function of the regulator valve is mainly related to the fixed pressure value, and will not directly affect the oxygen concentration, flow meter and other functions. However, in the actual use of the process, still need to pay attention to the following pressure-related factors: Compressor power: the power of the compressor is closely related to the performance of the oxygen generator. Plains area common 5L plains compressor power of 250W ~ 480W, while the plateau area oxygen generator compressor power is generally more than 480W. The higher the power of the compressor, the higher the oxygen pressure and flow rate it can provide.
Molecule sieve adsorption time
Adjusting the adsorption time of the molecular sieve will also affect the performance of the oxygen generator. Adjusting the adsorption and exchange time between the molecular sieve and the four-way valve can enhance the ability of the oxygen generator to inhale air, thereby increasing the oxygen production and correspondingly affecting the pressure of the oxygen generator.
The oxygen generator circuit board is about one-half the size of a cell phone, which is much smaller compared to the circuit board of a respirator of about 50*55cm. From some disassembly videos and circuit diagrams, the core components of the oxygen generator are mainly MCU, discrete components, pressure sensors, power management chips, jne. The core components of the oxygen generator are mainly MCU, discrete components, pressure sensors, and power management chips.
Conclusion:
Pressure monitoring and regulation of home oxygen concentrators is essential to ensure their proper operation. By optimizing factors such as operating pressure, oxygen outlet pressure, compressor power, and molecular sieve adsorption time, the performance and stability of the oxygen concentrator can be significantly improved to satisfy the oxygen demand of users. In addition, the core components inside the oxygen concentrator, such as pressure sensors and MCUs, also play an important role in ensuring that the equipment is able to monitor and regulate the relevant pressure parameters in real time, thereby enhancing the experience and safety of the oxygen concentrator.
