Description 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. Feature 1. 99.9% filtration efficiency (Beta 1000) and exactly precision from 1 to 100 micron 2. Depth layers strucure, high contaminant holding capacity and longer filter service life 3. High anti-pressure ability, proprietary process delivers superior efficiency and economical cost 4. High filtration efficiency of absolute PP melt blown cartridges, consistent filtration performance 5. Absolute PP filters are made of 100% FDA polypropylene materials, free of binder, surfactant and adhesive 6. Absolute PP melt blown filters have excellent chemical compatibility, so used in a wide range of applications Application Food & Beverage Microelectronics PCB industry Chemical/Industrial Water Treatment Pharmaceuticals Petrochemical Process Pre RO/ID Water Filtration Electronic Industry
