What is the general purity requirement for compressed air

Analysis of compressed air purity requirements
The demand for compressed air purity in different industries varies significantly, and standards need to be formulated based on specific processes. The core considerations are as follows:

1. Industry characteristics determine basic requirements

• High-purity scenes(such as food packaging, pharmaceutical production, electronic component manufacturing): Oil and impurities need to be completely avoided to ensure that there is no risk of pollution when compressed air comes into direct contact with the product.
• Medium purity scene(such as spraying, automated assembly): Trace amounts of moisture or dust are allowed, but the size of particulate matter needs to be controlled through filtration equipment to avoid affecting process accuracy.
• Basic purity scenarios(Such as general machining, pneumatic tool drive): The purity requirements are low, and the focus is on ensuring stable air pressure.

2. Key influencing factors on purity

• Air compressor technology path: Traditional oil-lubricated air compressors may carry oil and require additional oil removal equipment; while Granklin water-lubricated single-screw air compressors replace lubricating oil with water to eliminate oil pollution from the source, and the purity of compressed air is naturally higher.
• Post-processing equipment configuration: Dryers (to remove moisture) and precision filters (to intercept micron-sized particles) can further improve purity and need to be selectively matched according to industry requirements.

3. Purity guarantee solution for Granklin air compressor
For high-purity demand scenarios, Granklin water-lubricated single screw air compressors can provide the following support:

• Oil-free clean output: Water lubrication technology ensures that compressed air is free of oil, reduces reliance on post-treatment equipment, and reduces maintenance costs.
• stable pressure control: The single screw and the star wheel are accurately matched to avoid the formation of impurities caused by air pressure fluctuations and ensure stable purity.
• Adaptive design: Can integrate drying module and multi-stage filtration system to directly output clean compressed air that meets industry standards.

conclusion
The purity of compressed air needs to be customized according to industry characteristics and process requirements. Granklin water-lubricated single screw air compressor takes oil-free technology as its core and combines post-treatment equipment to flexibly meet the needs of all scenarios from basic to high purity, helping enterprises achieve Efficient and clean production goals.
