Air compressor filter element level

The filter element level of air compressor filters is usually in microns（ μ m) Represented in units, it is used to describe the size range within which filters can effectively remove particulate matter. Different applications require different levels of filters, which typically include:

1. Coarse filtration: usually at 25 μ M to 100 μ Within the range of m, it is mainly used to remove larger particulate matter, such as dust and particulate matter. This level of filter is usually used for pre filtration of air compressors to protect finer filters.
2. Precision filtration: usually at 1 μ M to 25 μ Within the range of m, it is used to remove smaller particles and solid particles. This level of filter is commonly used to provide cleaner air to meet specific application requirements, such as food processing and pharmaceuticals.
3. Ultra precision filtration: usually at 0.01 μ M to 1 μ Within the range of m, it is used to remove small particles, including bacteria, viruses, and small particles. This level of filter is typically used for high demand applications such as electronic manufacturing and healthcare.
   The selection of an appropriate filter level depends on the application requirements, and usually needs to be based on the properties of smoke, particulate matter, and liquid droplets. In general, a coarse filter is used for pre filtration, followed by precision or ultra precision filters to ensure the required air quality and dryness are provided. Different applications may require different levels of filters to meet standards for cleanliness and particulate matter control.
