Product Overview
PP Melt Blown Filter Cartridge 1 Micron 40 Inch is a high-end 40-inch 1μm ultra-fine PP melt blown filter cartridge, specially developed for scenarios requiring strict water quality pretreatment. Different from conventional 5μm/10μm coarse filters, this element adopts ultra-dense gradient fiber layout to achieve stable 1 micron absolute fine interception. The whole body is made of pure polypropylene raw material without any chemical adhesive, relying entirely on high-temperature melt-blown fusion molding, ensuring zero fiber shedding and zero secondary pollution. The optimized graded density structure greatly improves dirt holding capacity while maintaining ultra-fine precision, avoiding the defect that traditional fine filters are easy to block quickly. Standard 40-inch industrial size, 60mm outer diameter and 30mm inner diameter, perfectly compatible with all standard industrial filter housings. It is the core front-end protective filter for high-precision water treatment systems.
Working Principle
PP Melt Blown Filter Cartridge 1 Micron 40 Inch ultra-fine melt blown filter cartridge adopts scientific outside-in gradient depth filtration mechanism. When raw water flows through the filter layer, large particle impurities are firstly trapped by the outer loose fiber layer; medium impurities are intercepted in the middle transition layer; countless micro particles below 1μm are deeply captured by the compact inner fiber layer. The multi-stage progressive filtration structure changes the simple surface filtration mode of ordinary filters, realizing three-dimensional deep impurity interception. It effectively disperses dirt load, delays pressure difference rise, and maintains long-term stable ultra-fine filtration efficiency, ensuring consistent inlet water quality for downstream ultrafiltration, reverse osmosis and ultra-pure water equipment.
