APP Series Absolute PP Melt Blown Filter Cartridges


Hongtek APP Series Absolute PP Melt Blown Filter Cartridges are constructed with high-technology design that take advantage of flow pattern progressively from surface to inner center. Absolute PP melt blown filters have significant service life, accompanied by consistent high filtration efficiency. Absolute melt blown filters are manufactured with progressively graded density and 100% FDA approved polypropylene material, therefore, the absolute rate of PP filters could get to Beta 1000(99.9%) and have super-normal dirt holding capacity and longer service life than normal PP melt blown cartridges.

Advanced absolute melt blown filter cartridges are available in high performance grading from 1 to 100 microns, with fine micro porous structure for high removal efficiencies. Absolute PP melt blown cartridges can be used both in pre-filtration and final filtration in food & beverage, pharmaceutical and water treatment applications.

Construction of Absolute Melt Blown Filters

● The cross-section drawn of absolute melt blown filters

● Smooth surface finish and no loose fibers to release into process

● From inner layers to outer layers of absolute 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

● Distinct filtration zones for good dirt holding capacity and high clarifying filtration

● 100% FDA approved polypropylene for compatibility with wide range of process fluids

Working Principle of Absolute PP Filters


● The drawing is the working principle of layers structure depth absolute melt blown filters

● Layers filtration keep absolute PP filters high flow rate, good filtration efficiency and long service life

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

● Large particles are hold in outer layers of absolute PP melt blown cartridges which are constructed by coarse fibers

Installation of Absolute Melt Blown FiltersInstallation_Absolute_Melt_Blown_Filters.jpg

● Hongtek brand depth absolute melt blown filter elements installed in S.S filter housing

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

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

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

● High quality and economical cost absolute melt blown filters increase of longer service life and save much cost
