MFNP050‑40N‑ITT: 50μm 40‑Inch High Throughput Pleated Cartridge Filter
Introduction:The MFNP050‑40N‑ITT cartridge filters are 40‑inch large‑diameter pleated industrial filtration elements adopting inside‑to‑outside flow pattern. Constructed with multi‑layer gradient polypropylene media and full hot‑melt bonding structure without glue, MFNP050‑40N‑ITT delivers stable 50 micron particle retention performance. It effectively intercepts suspended solids, sediment, rust particles and colloidal impurities, providing reliable safety pre‑filtration protection for downstream RO, NF and UF membrane systems, reducing membrane fouling risk and extending membrane service lifespan. Large pleated area brings outstanding single‑element throughput, lowering the quantity of filter cartridges installed inside filter housings. Dimensionally matched to mainstream industry‑standard large‑flow filter vessels, MFNP050‑40N‑ITT supports quick replacement with built‑in lifting handle, widely used for industrial water treatment, circulating water purification, power plant water‑making and various EPC engineering procurement projects.

Working Principle
This High Flow Filter Cartridge MFNP050‑40N‑ITT operates on radial inside‑to‑outside filtration principle. Untreated process water flows into the inner cavity from the bottom opening of the cartridge, and flows radially outward through multi‑layer gradient polypropylene pleated media. Solid contaminants such as sediment, rust fragments and suspended particles are trapped on filter media surface and within pleated interlayers. Purified liquid flows outward and enters downstream pipelines and membrane equipment.
Benefiting from large effective pleated filtration area, MFNP050‑40N‑ITT keeps low initial pressure drop under high‑flow working conditions. As intercepted pollutants accumulate gradually, inlet‑outlet differential pressure will rise. Operators need to replace MFNP050‑40N‑ITT when pressure difference reaches recommended threshold, to restore system flow capacity and avoid excessive energy consumption. Gradient‑depth filter media combines surface filtration and depth‑filtration performance, improving overall dirt‑holding capacity for long‑time continuous operation.
Core Advantages
40‑Inch Large‑Diameter Pleated High‑Flow StructureMFNP050‑40N‑ITT features large outer diameter and ample pleated area for each element. Under the same system flow requirement, fewer cartridges are needed inside filter housing, decreasing spare‑parts inventory and lowering manual replacement workload for industrial sites.
Stable 50 Micron Gradient PP Filtration MediaMulti‑layer gradient polypropylene pleated media provides consistent particle retention. MFNP050‑40N‑ITT works as dependable safety pre‑filtration barrier before RO/NF/UF membrane systems, cutting particulate pollutant load and mitigating mechanical scratch risk for high‑cost membrane sheets.
All‑Polypropylene Hot‑Melt Welded AssemblyMedia, support layers and end caps of MFNP050‑40N‑ITT are full polypropylene material with thermal‑bond assembly, no adhesive added. Good acid‑alkali compatibility adapts to most industrial water conditions and eliminates risk of glue leaching into process fluid.
High Dirt‑Holding Capacity & Low Initial Differential PressureOptimized pleat geometry maximizes contaminant storage volume. MFNP050‑40N‑ITT can accumulate large amounts of impurities before reaching blocking differential pressure, extending service intervals and reducing overall filter operating expenditure. Low initial DP reduces pump energy loss during continuous running.
Standard Dimension & Convenient On‑Site MaintenanceMFNP050‑40N‑ITT is dimensionally built to fit widely‑used large‑flow filter vessel specifications. Integrated lifting handle enables fast cartridge change‑out. Multiple sealing material options including EPDM, silicone and nitrile are available to satisfy diverse liquid chemical properties and working temperature requirements.
