Folded filter is made of polyethersulfone. The polyethersulfone is the most advanced microporous membrane in the world. The polyethersulfone membrane pores account for more than 80% of the membrane volume. The pores has a microporous geometry, thus it can raise the filtration efficiency and throughp

The hydrophilic polytetrafluoroethylene membrane pleated filter is composed of advanced absolutely rated hydrophilic polytetrafluoroethylene membrane and high quality polypropylene.In addition to providing high porosity and permeability, PTFE Membrane Folding Filters provide high dirt holding capaci
