Is the grade of the pneumatic three-link filter low to high? The pneumatic Sanlian filter does not clearly indicate the level of the Trinity, but only has a difference in the filtering accuracy of the front oil and water filter. There are generally three kinds of thick, medium and fine. Generally, the inner filter element is a coarse filter with 50um filtration degree and the filter element is 20 ~ Medium filter of 30um filtration degree, 1 ~ The filtering degree of 5um is a fine (fine) filter. Each filter element can be installed on different three-link parts according to different needs.The filter element in the filter has better filtering effect, but it relatively affects the air flow and is easier to block. The thicker the filter element in the filter, the filter effect is relatively poor, but the more smooth the flow, it is not easy to block. So it is selected according to the usage requirements.
