Commonly used factory compressed air quality grade

Commonly used factory compressed air quality grades are usually evaluated based on the impurities and moisture content they contain. Common grades include industrial grade, medical grade and food grade. Here is a detailed introduction to these levels:

Industrial grade

  • Features: Industrial grade compressed air is suitable for most industrial applications, such as spraying, packaging and automated production lines. This level of compressed air is strictly controlled in oil content, moisture and dust particles to ensure the stability of the production process and product quality.
  • Usage: It is widely used in various industrial productions to meet general industrial needs.

Medical grade

  • Features: Medical grade compressed air has higher requirements for air quality and is usually used in medical equipment and laboratories. This level of compressed air needs to be deeply purified and filtered to ensure its purity and sterility.
  • Purpose: Mainly used in pneumatic tools, instruments, and ventilators in medical equipment and laboratories where pure air is needed.

Food grade

  • Features: Food-grade compressed air also has very high requirements for air quality and is usually used in areas such as food processing and packaging. This level of compressed air needs to comply with food safety standards to ensure hygiene and safety in food production.
  • Purpose: Mainly used for pneumatic tools, instruments and purges food contact surfaces in food processing and packaging equipment.

Other levels

In addition to the above levels, there may be other levels of compressed air quality classification based on the specific application scenarios and requirements. For example, high-precision compressed air is mainly used in occasions where air quality is very high, such as precision instruments, electronic manufacturing and pharmaceutical production; pure compressed air is the highest level of compressed air, which is usually used in extreme environments such as scientific research, semiconductor manufacturing and nuclear industry.

Evaluation Standards

The evaluation of compressed air quality levels is usually based on relevant national or international standards, such as China’s GB/T 13277 “General Compressed Air Quality Level” and the ISO 8573 series standards of the International Organization for Standardization (ISO). These standards stipulate the amount of solid particles, oil content and oil content in compressed air.

Practical Application

In practical applications, factories should choose appropriate compressed air quality levels based on specific needs and uses. For example, for automated production lines and precision instrument manufacturing, high-precision or pure compressed air should be selected; for general industrial uses and sprayingIn other occasions, industrial-grade compressed air can be selected.

In general, the selection of commonly used factory compressed air quality levels should be carefully selected according to specific needs and uses to ensure the stability of the production process and product quality.
