Talking about the filter selection of screw air compressor

In the post-processing equipment of screw air compressors, filters are also necessary and important. The function of the filter is to filter out the moisture and oil in the compressed air. The higher the level of the filter element, the higher the filtration accuracy. Air compressor filters are used in conjunction. Industries requiring high compressed air quality require multiple and multi-stage filter configurations.

　　 When configuring the filter, there may be two misunderstandings. The first misunderstanding is that the higher the accuracy of the air compressor filter, the better. In fact, this is not the case. It is not that the higher the accuracy of the air compressor filter, the better the filter effect of the air compressor. Choosing the appropriate air compressor filter is the most important.

　　Filter accuracy refers to the maximum diameter of solid particles that can be blocked by the air compressor filter element. The higher the filtration accuracy, the smaller the solid particles that can be blocked, but the easier it is to be blocked by large particles. When selecting an air compressor filter, if a high-precision filter is selected regardless of the occasion, it cannot guarantee that its filtration efficiency will increase, and its service life will also be affected.

　　 The second misunderstanding is that according to the required air quality, selecting a single air compressor filter corresponding to the processing accuracy can meet the requirements and save costs. Although the required air quality is determined by the processing accuracy of the selected single air compressor filter, if there is no pretreatment protection of the pre-lower-level air compressor filter, the high-precision filter element is very It will soon be blocked or damaged due to excessive load. This shortens the service life, speeds up the replacement frequency, and increases production costs in disguise.
