Many people do not understand the structure of Hydac hydraulic filter, but you’re not familiar with the basics of hydraulic filtration, then you in the filter of the procurement work is facing difficulties, so you need to understand the structure of Hydac hydraulic filter element.

“Paper” filter elements can also be made from polyester, which look similar to their cellulose counterparts. Realize polyester filters aren’t the most efficient material to filter with, but they’re inexpensive and aren’t very hygroscopic, meaning they don’t absorb water. This allows you to use a cheap filter in applications where water removal isn’t necessary.
Synthetic filter media are the current gold standard for quality of filtration. They are manufactured from synthetic glass fibers, which are very fine and consistent in texture. Multiple layers of differing quality are used to create a medium that is both extremely efficient and offers great dirt holding capacity. The problem with fine filtration is that the particles can clog the orifices, but the depth-type media of synthetic filters allows huge dirt retention, especially compared with other surface-type media.
