Specifications and standards for compressed air for enterprises

Compressed air specifications and standards for enterprises mainly involve the following aspects:

pressure requirements:

the pressure of the compressed air is usually required to be in a specific range of 0.7 to 1.0 megapascals (MPa). This standard helps to ensure the stability and efficiency of the compressed air system, while avoiding safety hazards caused by equipment damage or improper operation.

Temperature requirements:

the temperature of the compressed air generally does not exceed 40 degrees Celsius. Controlling the temperature within this range can avoid adverse effects on equipment and processes, such as equipment overheating, performance degradation or damage.

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. This can prevent moisture from causing corrosion and pollution to equipment and processes, and ensure the smooth progress of the production process.

Oil content requirements:

the oil content in the compressed air also needs to be controlled at a low level, and the oil content is generally required to be below 5 mg/m3. The oil content is limited to avoid pollution to equipment and processes, and to ensure product quality and production safety.

Purification requirements:

the impurities and particles in the compressed air need to be kept at a low level, usually requiring a filter grade below 5 microns to ensure the purity of the air. This helps prevent impurities from polluting equipment and products, and improves production efficiency and product quality.

In addition, for specific industries such as food factories, the implementation of compressed air standards may be more stringent. For example, food factories often need to achieve higher levels of purity to ensure food safety and hygiene. In this case, international standards such as ISO 8573 may be used to specify the maximum allowable contents of solid particles, water vapor and oil in the compressed air.

In general, the specifications and standards for compressed air used by enterprises are designed to ensure the quality and safety of compressed air to meet the needs of different industries and production processes. These standards can be adjusted and customized according to the needs and process characteristics of specific enterprises.
