Product Description

Product Description

PP cotton melt-blown filter cartridge

PP cotton melt-blown filter, also known as PP cotton filter, melt-blown filter/melt-blown PP filter, PP melt-blown filter, PP filter, is made of polypropylene ultrafine fibers through thermal melting and entanglement without using any chemical adhesives. The PP polypropylene fibers self-adhere randomly in space to form a three-dimensional microporous structure, integrating surface, deep, and coarse filtration. Due to the high filtration precision and dirt holding capacity formed by fibers and density in the diameter direction of the filter, it features a deep filtration structure with a gradual change in pore size from sparse outside to dense inside, resulting in strong dirt holding capacity. It can effectively remove suspended solids, particles, rust, and other impurities from the fluid, achieving high filtration efficiency and long service life.
