filter membrane for medical pharma and food grade

PP pleated filter cartridge is used to filter the liquid. It is made by folding polypropylene microfiber membrane. The folded filter element maximizes the filter area and reduces resistance. The filter element and shell are welded instead of glued for maximum integration thus minimizing contamination. It provides excellent filtration performance for many liquids and has good chemical stability.

PP pleated filter cartridges are used in many industries, such as chemical, RO water treatment, microelectronics, spraying, etc.
