EPD Depth Filter Cartridges

Electronics-grade polypropylene EPD Depth Filter Cartridges are power-flushed filter cartridges designed to meet the special needs of the electronics and high-purity chemical industries. Raw materials of construction were specifically chosen on the basis of their chemical compatibility and low extractables when exposed to typical process chemicals and solvents. To remove all manufacturing debris and minimize extractables, each cartridge module is pulse-power flushed until the rinse effluent reaches 17+ Megohm-cm and less than 3 ppb TOC. Each cartridge module is also individually tested to ensure it is integral. EPD cartridges are rated at 99.9% efficiencies at the rated pore size. Our design criteria and special procedures allow us to provide the highest quality electronics-grade cartridges.
