Quality Filtration: The wound water filter features a deep bed filtration function with a honeycomb structure that is dense inside and sparse outside. It 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, depending on usage. Multiple Advantages: Offers high filtration accuracy, high flow rate, low pressure drop, high compressive strength, high dirt-holding capacity, non-toxic and tasteless materials, and no risk of secondary pollution. Maximum Operating Temperature: 80°C Applicable pH Range: 1–13 Maximum Operating Differential Pressure: 4.2 Bar Recommended Replacement Differential Pressure: 2.4 Bar Material: Pure Polypropylene Microfibers The string wound filter is a type of water filter constructed by precision-winding textile fiber lines around a porous polypropylene core, forming a thin, dense honeycomb structure. It effectively removes suspended solids, particles, rust, and other impurities from water, offering excellent filtration performance. Additional Features: High filtration accuracy, low pressure differential, high flow capacity, high contaminant loading capacity, and long service life. The pore size is smaller on the inside and larger on the outside, enabling efficient depth filtration. The wound construction withstands high filtration pressures. Effectively removes suspended matter and particulates from water.
