Common air supply pressure in the workshop

What is a workshop air supply?

A workshop air supply typically refers to a compressed‑air system that provides power to various pneumatic devices, tools, and automated actuators. Its stability and pressure parameters directly affect production efficiency and equipment lifespan.

Common compressed‑air pressure ranges

• General pneumatic tools: 0.4–0.7 MPa (4–7 bar), such as impact wrenches, spray guns, and clamping devices;
• Automated control components: 0.3–0.6 MPa (3–6 bar), suitable for cylinders, solenoid valves, sensors, and the like;
• Special process requirements: Certain blow‑cleaning, drying, or precision‑assembly applications may employ 0.2–1.0 MPa, which must be set according to the equipment nameplate specifications.

Considerations for pressure selection

In practical applications, one should balance the equipment’s rated pressure, pipeline pressure drop, fluctuations in air consumption, and energy‑saving requirements. It is recommended to install a pressure gauge and a filter‑regulator valve at the end of the main line, and to perform regular calibration to prevent abnormal operation caused by overpressure or insufficient pressure.
