Oil-free standard for compressed air

The oil-free standard for compressed air is based primarily on ISO 8573-1. According to this standard, the highest grade of oil-free compressed air, Class 0, requires an oil content of less than 0.01 mg/m & sup3;. In addition, different application areas have specific requirements for the oil-free standard of compressed air:

medical field:

in the Chinese Pharmacopoeia and GMP (Good Manufacturing Practice), it is stipulated that the oil content of compressed air should be less than or equal to 0.1 mg/m & sup3;.

The oil content of medical compressed air gas must be ≤ 0.1 mg/m & sup3 according to European Pharmacopoeia;.

diving breathing with compressed air:

in the United States and China, oil content <5 mg/m & sup3; is required;.

In the UK, the standard is more stringent, requiring oil content <1 mg/m & sup3;.

These standards are formulated according to specific application needs and conditions to ensure the purity and safety of compressed air. In practical application, the relevant standards and regulations should be consulted according to the specific situation.

In addition, from a technical point of view, the compressed air that meets the oil-free standard is usually produced by an oil-free air compressor. Such compressors do not use oil for lubrication during the compression process, thereby avoiding the risk of oil contamination. In some occasions with high air quality requirements, such as medical treatment and food processing, the application of oil-free compressed air is very important.

In general, the oil-free standard of compressed air varies depending on the application field and the country, but it is to ensure air quality and use safety as the starting point. In actual operation, the corresponding standards and regulations should be strictly observed.
