What are the eight pressures of the air compressor?

The air compressor refers to "eight pressures", in the industry usually refers to its working pressure of 8 bar (Bar) or equivalently, 0.8 MPa (MPa). This is a common pressure level in industrial and commercial fields, and is suitable for a variety of basic applications, including but not limited to workshop air supply, pneumatic conveying systems, and automation equipment.

Detailed analysis

1. pressure Unit Conversion:
   • 1 bar is equal to 0.1 megapascals (MPa).
   • Thus, 8 Bar is equal to 0.8 megapascals (MPa).
2. Scope of application:
   • the working pressure of 8 bar belongs to the low to medium pressure range, which is suitable for a variety of industrial and commercial needs.
   • The working pressure of low-pressure air compressors is usually between 0.7 and 1.2 MPa, which is suitable for common applications such as air tools, painting, painting, packaging machinery, etc.
   • Medium-pressure air compressors operate at pressures between 1.2 and 3 MPa, and while 8 bar (0.8MPa) is near the lower end of this range, they still meet the basic needs of many medium-pressure applications.
3. International and National Standards:
   • according to the ISO 1217 international standard, air compressors can be divided into four categories: low pressure, medium pressure, high pressure and ultra-high pressure. In Chinese standards, it is similarly divided into general air compressors, high-pressure air compressors and ultra-high-pressure air compressors. However, these criteria are mainly used for classification and do not directly define the specific applications or needs of the "eight pressures.
4. Precautions:
   • the actual operating pressure may be adjusted depending on the application requirements. In some specific cases, a higher or lower working pressure may be required.
   • When choosing an air compressor, in addition to considering the working pressure, it is also necessary to comprehensively consider factors such as exhaust volume, equipment use environment, air source quality, and maintenance costs.

In summary, the "eight pressures" referred to by the air compressor, that is, 8 bar (Bar) or 0.8 MPa (MPa), is a pressure level widely used in industrial and commercial fields.
