NPP Series Nominal PP Melt Blown Filter Cartridges are made of 100% FDA approved polypropylene material, without binders, additives and lubricants. PP melt blown filter elements are manufactured by different pore diameter of spray nozzles melt blown machines. PP melt blown filters are multi-layered construction with fine fibers in inner layer when in outer layer fibers are coarse, so have progressive contaminant removal efficiency and consistency of good proformance.
PP melt blown filter cartridges are high dirt holding capacity, low pressure drop, high flow rate, good chemical resistance, no fibre release, long service life and effectively filtration for suspended particle, sediment and other kinds of impurities. PP melt blown cartridges are economical and classical filter media, widely used in liquid prefiltration industries.

| Construction of PP Melt Blown Filter Cartridges | ||
 | ● The cross-section drawn of PP melt blown filter cartridges ● From inner layers to outer layers of PP filters the fiber is fine to coarse ● Multilayered structure and depth filtration pattern ensure good filtration efficiency ● Formed by thermal bond without using of any binders, adhesives and and lubricants ● 100% FDA approved polypropylene for compatibility with wide range of process fluids | |
Working Principle of PP Melt Blown Cartridges | ||
 | ● The drawing is the working principle of layers structure depth pp melt blown filter cartridge ● Layers filtration keep pp melt blown filter high flow rate, good filtration efficiency and long service life ● Large particles are filtered in outer layers of melt blown cartridges which are constructed by coarse fiber ● Small particles pass the outer layers, then filtered by inner layers wich made of fine fiber and high precision | |
Installation of 40" 5 Micron PP Melt Blown Filter Cartridges
● Hongtek brand depth PP melt blown filters used for pre RO water filtration
● The central of PP filter elements are still no polluted, so that keep liquid clear after filtration
● After used PP filters compare with before used can apparent know the good efficiency filtration
● High quality and reasonable price melt blown cartridges increase of longer service life and save much cost
● No fiber drop out, high dirt holding, low pressure drop, high flow rate and high pressure resisting capability
