What is the pressure of an air compressor in a general factory

The pressure range of an air compressor in a general factory is usually in the range of0.6-1.0 Megascals (MPa), which is approximately 6 – 10 kilograms of force per square centimeter (bar), depending on the application scenario and equipment requirements. The following is a detailed analysis:

1. General application scenarios

• Mainstream pressure range：
  Most factories use0.7-0.8 MPa（7-8 bar）compressed air is suitable for common needs such as pneumatic tools, automation equipment, and purging cleaning. For example:
  • Pneumatic assembly line for parts and components in automobile manufacturing.
  • The power source of food processing equipment.
  • Cylinder drive for automated assembly lines.

2. Special needs scenarios

1. high-pressure demand：
   Certain precision machining or high-pressure equipment requires1.0-1.2 MPa（10-12 bar）, such as:
   • Fill the high-pressure cylinder.
   • Clamping device for precision machining.
2. low pressure demand：
   Light equipment or special processes may be used0.4-0.6 MPa（4-6 bar）, for example:
   • Low air pressure control for spraying operations.
   • Some low-pressure pneumatic tools.

3. Relationship between compressor power and pressure

• Small compressor (power <15kW)：
  pressure is usually6-8 bar（0.6-0.8 MPa）, suitable for low-pressure scenarios (such as painting, pneumatic tools).
• Large compressor (power>15kW)：
  pressure up to8-14 bar（0.8-1.4 MPa）, meet high load requirements (such as drilling, punching).

4. Industry standards and specifications

• National standard recommendations：
  The recommended industrial compressed air pressure range is0.6-0.8 MPa, but needs to be adjusted according to the actual process.
• additional requirements：
  • moisture control: Pressure dew point needs to be as low as-20℃ to-40℃(Required in cold areas or sensitive processes such as painting-70℃）。
  • flow matching: The flow rate needs to be selected based on the number of equipment (for example, the production line needs 30-50 cubic meters per minute).

5. Suggestions for choosing pressure

1. Reference equipment specification: Confirm the working pressure range of the pneumatic tool or equipment.
2. consulting engineer: Design the system based on factors such as process requirements, pipe length, and pressure loss.
3. energy saving and safety: Avoid excessive pressure causing equipment loss, or too low pressure affecting efficiency.

summary: Factory air compressor pressure is usually set to0.6-1.0 MPa（6-10 bar）, needs to be flexibly adjusted based on specific processes, equipment power and industry standards, and professional evaluation is required if necessary.
