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 based 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 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 String Wound Filter Description: A string wound water filter is constructed by precision winding textile fibers around a porous polypropylene core, forming a tightly packed honeycomb structure. This design effectively removes suspended solids, particles, rust, and other impurities from water, providing excellent filtration performance. Additional Features: High filtration accuracy, low pressure differential, high flow capacity, high contaminant loading capacity, and extended service life. The pore size is smaller on the inside and larger on the outside, enabling effective depth filtration. The wound construction withstands high filtration pressures. Effectively removes suspended matter and particulates from water.
