Compressed air quality for general use in the plant

The compressed air quality standards generally used in the factory mainly include the following aspects:

oil content: The oil content in compressed air is usually required to be low to avoid pollution to equipment and processes. In general, the oil content should be less than 5mg/m3.

Water content: The moisture content in compressed air is also required to be controlled at a low level, usually less than 0.1mg/m3, to prevent moisture from adversely affecting equipment and product quality.

Temperature: The temperature of the compressed air generally does not exceed 40 degrees Celsius to avoid affecting the equipment and process. In practical applications, the temperature usually does not exceed 37°C.

Pressure: The pressure of compressed air is generally required to be within a specific range, usually 0.7 to 1.0 MPa (MPa), and the specific pressure value is determined according to actual needs.

Purification requirements: The impurities and particles in the compressed air are required to be low, and the filtration level is usually below 5 microns to ensure the purity of the air. In some special applications, such as food and beverage industry or medical and health fields, there are higher requirements for the impurity content of compressed air to ensure product quality and safety.

In summary, the compressed air quality standards generally used in factories mainly include oil content, water content, temperature, pressure and purification requirements. These standards are essential to ensure safety and efficiency in the production process, and directly affect the life of the equipment used and the quality of the product. Therefore, when selecting and using compressed air, the factory should strictly follow these quality standards.
