Standard for the Use of Compressed Air for Industrial Use

The use of industrial compressed air standards mainly include the following aspects:

pressure requirements:

typically, the pressure range for industrial compressed air is between 0.7 MPa(7 bar) and 1.0 MPa(10 bar). This is a common standard operating range for pneumatic tools, automation equipment, etc. in many general factories.

Certain applications may require higher gas pressures, such as heavy machinery, pneumatic fixtures, or certain process equipment, which may require 1.2 MPa(12 bar) or more.

In addition, some lightweight applications may require lower gas pressures, such as 0.5 MPa(5 bar) or less.

Temperature requirements:

the temperature of the compressed air is generally not more than 40 degrees Celsius to avoid the adverse effects of high temperature on the equipment and process.

Requirements for dryness:

the moisture content in the compressed air should be low, and the dew point temperature is usually required to be below -20 degrees Celsius to prevent corrosion and pollution.

Oil content requirements:

the oil content in the compressed air needs to be kept at a low level, and the oil content is generally required to be below 5 mg/m3 to prevent the oil from polluting the equipment and process.

Purification requirements:

the impurities and particles in the compressed air also need to be controlled at a low level, usually requiring a filter grade below 5 microns to ensure the purity of the air.

Other quality requirements:

the humidity of the compressed air is generally required to be less than 50%.

The solid particles in the compressed air are required to be less than 5 μm.

Compressed air should not contain malodors or odors.

It should be noted that different countries and regions may have different standards for compressed air, and the specific needs and process characteristics of different plants will also affect these standards. Therefore, in practical applications, selection and judgment should be made according to local regulations and standards, as well as the specific conditions of the factory. At the same time, when designing and selecting the compressed air system of the factory, it is recommended to consult an engineer or compressed air equipment supplier to ensure that the work requirements are met and efficiency is maintained.
