Wire wound filter element is a deep layer filter element used for low viscosity and low impurity quality filtration. It is made by precisely winding textile fiber thread (polypropylene thread, degreased cotton thread, etc.) onto a porous framework (polypropylene or stainless steel) according to a specific process. It has a honeycomb like structure that is sparse on the outside and dense on the inside, effectively removing suspended solids, particles, rust and other impurities in the fluid, and has excellent filtration characteristics.
