Product Description PRE III depth cartridge filter (Melt-blown depth filter) is made of silicone-free material as 100% polypropylene media. This filter is permitting the creation of multiple filtration zones. This design produces a gradient pore structure, which effectively captures large particles in the outer sections while providing highly efficient and consistent removal of smaller particles in the innermost sections. Product Feature - 100% all polypropylene - Exnt chemical resistance - High dirt holding capacity - High flow rate and low differential pressure - FDA complied polypropylene material Product Specification / Models Application / Models Electronic Industry - Etching solution, electro plating Chemical Industry - Adhesive, Solvent, Surfactant, Chemical liquid Food and Beverage Industry - Wine, Potable water, Beer, Soft drink, Brewery, Sugar, Edible Oil General Process Industry - Pre-filtration for DI and RO system, Process water
