High Flow Filter Cartridge 20 Micron 40 Inch: Ultra-High Flow Large Diameter Filter For Heavy Turbidity Raw Water Pre-Filtration
Introduction:If you are sourcing High Flow Filter Cartridge 20 Micron 40 Inch for heavy turbidity raw water, high-sediment river water, mining water and large-flow first-stage industrial pre-filtration, this 20μm large-diameter pleated filter is the ideal coarse-grade solution. Designed for extreme high-turbidity working conditions, it features ultra-open pleated structure and maximum water permeability while stably intercepting particles above 20μm. It efficiently removes coarse sediment, rust debris, large flocs and suspended solids, drastically reducing raw water turbidity and protecting downstream precision filters and RO membrane systems from heavy particle contamination. With ultra-low pressure drop, extreme anti-clogging performance and minimal cartridge quantity required, it greatly reduces operating and maintenance costs for large-scale industrial water treatment plants.

Product Overview
High Flow Filter Cartridge 20 Micron 40 Inch is a professional coarse-grade high-flow filter developed specifically for high-turbidity raw water pretreatment. Compared with 1μm, 5μm and 10μm high-flow fine and medium filters, the 20μm model adopts optimized large-opening deep pleated media to achieve maximum flow rate and outstanding anti-blocking capability. The entire filter is made of 100% virgin polypropylene with full thermal welding technology, no glue or chemical additives, ensuring zero secondary pollution and excellent chemical inertness. The 115mm enlarged outer diameter greatly increases the effective filtration area, enabling single-cartridge ultra-high throughput that far exceeds standard small-diameter filters. Standard 40-inch length matches all mainstream large-flow filter housings, supporting fast replacement and continuous stable operation. It is the best cost-effective first-stage barrier for heavily polluted raw water and high-load industrial water systems.
Working Principle
This 20 micron 40-inch high flow filter adopts outside-in pleated surface filtration principle. When high-turbidity raw water carrying massive coarse sediments flows through the deep pleated layer, oversized gravel, thick rust scale and large flocs are intercepted on the outer pleat surface. All suspended particles larger than 20μm are uniformly trapped by the high-strength PP filter media. The wide-gap pleated structure provides unobstructed flow channels, avoiding surface blockage and pressure surge under high-load raw water conditions. The fully thermally sealed integral structure prevents liquid bypass and ensures 100% effective filtration. The rigid reinforced inner core maintains stable structural shape under long-term high-flow impact and differential pressure fluctuation, delivering consistent and reliable coarse filtration performance.

Core Advantages
Extreme anti-clogging performance:
20μm large-opening pleated structure is specially optimized for heavy-turbidity raw water with massive sediments, effectively avoiding frequent blockage and reducing maintenance downtime.
Maximum single-cartridge flow rate:
Open-type deep pleated design minimizes flow resistance, achieving ultra-high water throughput and greatly reducing the total number of required filter cartridges.
Heavy-duty dirt holding capacity:
Large filtration area stores massive coarse pollutants, extending service life significantly and lowering long-term operating costs.
Pure glue-free safe structure:
Full thermal welding without chemical adhesive ensures no organic leaching, suitable for municipal water, industrial process water and circulating water systems.
Wide chemical compatibility:
Virgin polypropylene material resists weak acid, weak alkali and neutral liquids, adapting to various complex industrial water conditions.

FAQ
Q1: What is the advantage of 20μm high flow filter?
A1: It has the largest flow rate and strongest anti-clogging ability among conventional high-flow filters, perfectly solving the blockage problem of high-turbidity raw water and greatly reducing replacement frequency.
Q2: Will 20μm filtration affect downstream water quality?
A2: No. It only intercepts large coarse impurities as the first-stage barrier, protecting downstream 10μm/5μm/1μm fine filters and improving the overall service life of the system.
Q3: What is the maximum working temperature?
A3: The maximum continuous operating temperature is 80℃, higher than ordinary melt-blown filters, suitable for most industrial circulating water environments.
Q4: Can customized end caps and sizes be made?
A4: Yes, DOE, SOE and other end cap styles, as well as customized lengths and special micron grades are available for bulk orders.
