General: A: Wider filtration precision, large flow rate of filtering, small pressure difference, high efficiency and stability. B: Due to themselves melting between the fused fibers, multi -layer structure of layer and layer adhesion, it is non-layered and non-shedding that makes good rigidity and stability of microporous. C: Because of the stability control of the filtering precision, cartridges can be accurately used according to various requirements and different environment. Scope of Application: Used for drinking water purification and pre- filtering Beverages, wine maker and edible oil manufacturers, all kind of filtration such as slurry; chemical raw materials, organic solvents; glue, latex, ordinary glue manufacturing, machine oil cutting oil; and for PCB liquid filtration, Electric Painting (ED), the chemical liquid filtration; industrial water, electronic electroplating liquid filtration; pre- filtration for pool water cleaning; imaging with liquid and the ink filtering etc.
