The working pressure range of air compressors varies according to their type, specifications and usage scenarios. The following information is based on different sources and authoritative sources:
1. low pressure air compressor
- working pressure range: It is usually between 0.4 MPa and 1.2 MPa. It is also said that the working pressure of the low-pressure air compressor is usually between 0.7 and 1.2 MPa. Converted to bar, this is equivalent to 4 to 12 bar or 7 to 12 bar.
- Application Scenarios: Suitable for scenes that do not require high pressure, such as light pneumatic tools, spraying equipment, inflatable toys, inflators and other small equipment.
2. medium pressure air compressor
- working pressure range: Usually between 1.2 MPa and 4.0 MPa, there is also a saying that the working pressure range of the medium pressure air compressor is between 1.2 and 3 MPa, that is, 12 to 30 bar.
- Application Scenarios: Suitable for applications with medium pressure requirements, such as production line pneumatic tools, pneumatic conveying systems, printing and packaging equipment, pharmaceutical and food industries, automotive maintenance and painting, etc.
3. high pressure air compressor
- working pressure range more than 3 MPa, it is also said that the working pressure of the high-pressure air compressor is usually between 4.0 MPa and 40.0 MPa, and can even reach more than 100 MPa. Converted to bar, this means more than 30 bar and even more than 1000 bar.
- Application Scenarios: Suitable for applications requiring high-pressure gas supply, such as high-pressure gas cylinder inflation, air tightness testing, high-pressure synthesis reactions in the oil and gas industry, chemical industry, wellhead pressurization in oil extraction, and precision control in pneumatic tools.
4. considerations
- specific pressure: The working pressure of an air compressor not only depends on its type, but is also affected by specifications and usage scenarios. Therefore, when choosing an air compressor, it is necessary to determine the required pressure range according to the actual gas demand and use conditions.
- Safety factor during the pressurization process, you need to always pay attention to the pointer on the pressure gauge to ensure that the pressure reaches the standard, and at the same time avoid excessive pressure, otherwise it may affect the operation of the air compressor and may even leave a safety hazard.
In summary, the pressure range of air compressors ranges from low pressure to high pressure, depending on their type, specifications and usage scenarios. When choosing an air compressor, it is necessary to consider comprehensively according to actual needs.
