PP Pleated Filter Cartridge - Free of Any Adhesive

Polypropylene(PP) Pleated Filter Cartridge is made by hot-melt bonding process with PP ultrafine fibers (fibers randomly form a three-dimensional microporous structure in space), without any adhesive (filter cartridge housing, center rod, end cap, etc.), produced in a clean environment (no pollution, no leakage). It has the characteristics of large membrane filtration area, large dirt holding capacity, low pressure difference, and long service life. The filter cartridge is made of 100% pure PP material, with a wide range of chemical compatibility. Our products are finely designed for different application scenarios to meet the different needs of customers.
