For industrial water pretreatment and RO membrane protection projects, plant managers and filtration purchasers select reliable Liquid Filters and Self Cleaning Filter to remove suspended particles and reduce system maintenance burden. Original Pentair RFM high flow filter cartridge often comes with high cost and long delivery cycles. Our drop-in replacement filter cartridge adopts radial pleated polypropylene media, fully matching the dimension, end cap connection and inside-to-outside flow design of Pentair RFM series. It provides consistent high-flow filtration performance and serves as a cost-saving spare part for industrial water pretreatment and RO pre-filtration systems.
Product Introduction
This Pentair RFM high flow filter cartridge replacement is specially designed for industrial water pretreatment and liquid purification. As the core consumable of industrial water filter systems, this high flow filter cartridge can work together with self-cleaning filter to construct multi-stage pretreatment workflows. It effectively captures sediment, rust particles and suspended solids, minimizing particle load entering downstream RO membranes and precision filters. Our replacement cartridge adopts high-purity polypropylene radial pleated media, maintaining the same size, sealing structure and end cap design as the original Pentair RFM filter cartridge. No modification to the existing filter housing is required during installation. Multiple micron ratings are available from 1μm to 70μm. It keeps stable filtration efficiency and helps water treatment plants, chemical factories and food processing facilities cut annual spare part procurement expenses.
Working Principle
This Pentair RFM equivalent high flow filter cartridge adopts inside-to-outside flow path. Untreated raw liquid flows into the central inner core, then passes radially outward through multi-layer radial pleated filter media. Solid contaminants are trapped inside the pleats of filter media, and clean liquid flows out from the cartridge outer surface. The radial pleat design maximizes effective filtration area, bringing excellent dirt holding capacity and high liquid throughput. When paired with upstream self-cleaning filter, most coarse impurities are intercepted in advance, slowing differential pressure rise and extending the service life of the high flow filter cartridge.
