Hangzhou Tanvi Filtering Equipment Co., Ltd sell "PP Pleated Filter Cartridge"

These pleated PP filter cartridges are widely used for pre-filtration and final filtration of liquids and gases in the pharmaceutical industry. The filter media is made from ultra-fine polypropylene fibers, with support layers, cage, and core also in polypropylene, joined by hot-melt welding without adhesives — so no fiber release occurs.
