The filtering principle of Pall filter element

Pall filter element uses porous media to remove contaminants from the fluid. The filter is often considered a simple mesh or sieve. In fact, the filter material produced by Pall has depth. The result of the "curved channel" plays an auxiliary role in the removal of pollutants. Particles can be trapped on the surface or in the medium layer, thus improving the dirt holding capacity. If it is a simple screen that can intercept particles with a size larger than its pore size, it may also be that multiple particles hit the same filter hole at the same time. Properly increasing the area of the filter can prolong the service life of the filter. Normally, the filter area is doubled and the service life is extended to 2-4 times.
