The quality of the filter element is more important to judge from the quality of the filter element. Therefore, how to identify the quality of the filter element is particularly important.

The first choice is to look at its internal skeleton and internal and external support network, must be high strength, zero pollution, no burr, no chemical reaction. Only in this way can we ensure normal operation.

Secondly, we should pay attention to the high performance filter material in the filter element. Must be made of chemical inert fiber and high strength resin, filter aperture to small and uniform, thickness to be reasonable and appropriate. Don't underestimate thickness, which is also extremely important.

Third, at the present stage, the filter element generally adopts these two methods, namely, the mechanical method is used for coarse separation, and the affinity condensation method is used for fine separation. The right way gets twice the work.

In addition, the bonding method used by high-quality filter elements is also very advanced. Adopt longitudinal seam bonding mode to ensure no leakage at the bonding point. Only in this way can we ensure the reasonable use of materials, avoid waste, save raw materials and save expenses.
