Quality Filtration: The string wound water filter features a deep bed filtration function with a honeycomb structure that is dense inside and sparse outside. This sediment filter can reduce 99.99% of sand, scale, rust, sediment, and particles. High Capacity: The filter can process 20,000 to 30,000 gallons depending on water quality. It is recommended to replace the filter every 3 to 6 months for optimal performance in an average household, based on usage. Multiple Advantages: Offers high filtration accuracy, large flow rate, low pressure drop, high compressive strength, high dirt-holding capacity, non-toxic and tasteless materials, and no secondary pollution. Maximum Operating Temperature: 80C Applicable pH Range: 113 Maximum Operating Differential Pressure: 4.2 Bar Recommended Replacement Differential Pressure: 2.4 Bar Material: Pure polypropylene microfibers The string wound filter is designed with precision-wound textile fibers on a porous polypropylene core, forming a fine, dense honeycomb structure that effectively removes suspended solids, particles, rust, and other contaminants from water, providing excellent filtration performance. Key Benefits: High filtration accuracy, low pressure drop, high flow rate, high contaminant capacity, and long service life. The filter has a gradient pore structuresmaller pores on the inside and larger on the outsideenabling efficient depth filtration. The string wound design withstands high filtration pressures. Effectively removes suspended matter and fine particles from water. Color: White Material: Polypropylene Size: Length: 250 mm Pore Size: 10 m Outer Diameter:
