Common factory compressed air quality grade

The quality grade of compressed air in common factories is usually evaluated according to the impurities and moisture content, and the common grades include industrial grade, medical grade and food grade. The following is a specific description of 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 more stringent in the control of oil content, moisture and dust particles to ensure the stability of the production process and product quality.
• Use: Widely used in various industrial production 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.
• Use mainly used in medical equipment and laboratory pneumatic tools, instruments and ventilators and other occasions that require pure air.

Food Grade

• features: Food-grade compressed air also has very high requirements for air quality, and is usually used in food processing and packaging. This level of compressed air needs to meet food safety standards to ensure hygiene and safety during food production.
• Use mainly used for pneumatic tools, instruments and purging of food contact surfaces in food processing and packaging equipment.

Other grades

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

Evaluation standard

compressed air quality rating is usually based on national or international standards, such as China's GB/T 13277 "General Compressed Air Quality Rating" and the International Organization for Standardization (ISO) ISO 8573 series of standards. These standards for compressed air in the solid particles, oil and oil content, etc. to make the amount of regulation.

practical application

in practical applications, the factory should select the appropriate compressed air quality level according to specific needs and uses. For example, for automated production lines and precision instrument manufacturing and other occasions, you should choose high-precision or pure-grade compressed air; and for general industrial use and spraying and other occasions, you can choose industrial-grade compressed air.

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