MICROPP pleated cartridge has been developed to meet the process needs and throughput requirements of the Pharmaceutical, Food & Beverage, Electronics, Chemical, and other critical industries. MICROPP pleated cartridges are used to filter liquids where high efficiency, low pressure drop, robust debris holding capacity and long life are essential. These filters can be used as a pre-filter or as a final filter depending on the application. MICROPP filter cartridges deliver high filtration efficiency and consistent filtration of fluids in a wide range of applications. All cartridge hardware components are made up of polypropylene and approved for use in critical process applications. MICROPP pleated cartridges are manufactured and assembled in a clean room environment to minimize the possibility of contamination. MICROPP cartridges are available in a wide range of configurations and end connections to fit most of the commercially available filter housings.
