Puritech Polypropylene Pleated Filter Cartridges

Puritech Polypropylene pleated filter cartridges are manufactured from the raw materials permitted by FDACFR21. This filter cartridge tolerates a variety of chemical solvents, used in the filtration of ordinary or corrosive fluid. We offer both nominal and absolute filter cartridges with pore size: 0.2~30μm, 10inch~40inch different length and full connector type for options. The large filtration surface area ensure long service life and low initial pressure drops. All hardware components are high purity polypropylene materials for use in critical process applications. All filter cartridges are manufactured and assembled in a clean room environment to minimize the possibility of contamination.
