Description of Water Prefiltration
WECHANFIB polypropylene melt-blown filter adopts a new process, so that the whole filter has a very hard mechanical properties, the pressure resistance is more than 2 times that of ordinary melt-blown filter, and can be applied to some high viscosity and high solid content of the feed liquid. The process of melt-blowing makes it have a high contaminant capacity and can withstand more impurities. It has better good effect and low resistance to filtration of granular materials, such as metal paint.

The wire-wound filter element is made of textile fiber (polypropylene, defatted cotton, glass fiber, polyester) precisely wound on the porous (PP, stainless steel) skeleton according to a specific density, with a honeycomb structure. Suitable for low viscosity, low impurity filtration, can effectively remove suspended matter, particles, rust and other debris in the material liquid, with very good filtration characteristics.
