EPP Series PP Melt Blown Filter Elements with Cores


EPP Series PP Melt Blown Filter Elements with Cores are manufactured of polypropylene complying with FDA, free of binder, surfactant and adhesive, accompanied by broad chemical compatibility. PP melt blown filter elements are robust and each high-efficiency polypropylene melt blown depth filter has an internal polypropylene core for added strength. Melt blown filter elements utilize a multi-layered construction for progressive contaminant removal efficiency and longer filter life. Hongtek innovatively creates PP water filter elements with superior performance and consistency, which are widely used in RO pre-filtration, microelectronics, food & beverage and process water industries.

Working Principle of PP Water Filter Elements with Cores

● The drawing is the working principle of layers structure depth PP filter elements

● Large particles are hold in outer layers of PP water filter elementss which are constructed by coarse fibers

● Small particles pass the outer layers, then filtered by inner layers wich made of fine fiber and high precision

● Layers filtration keep melt blown filter elements high flow rate, good filtration efficiency and longer service life

Installation of PP Melt Blown Filter Elements with CoresInstallation_Absolute_Melt_Blown_Filters.jpg

● Hongtek brand depth PP filter elements with cores installed in S.S filter housing

● The central of absolute PP filter elements are still no polluted, so that keep liquid clear after filtration

● After used PP filter elements compare with before used can apparent know the good efficiency filtration

● No fiber drop out, high dirt holding, low pressure drop, high flow rate and high pressure resisting capability

● High quality and economical cost PP water filter elements increase of longer service life and save much cost
