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: 80C Applicable pH Range: 113 Maximum Operating Differential Pressure: 4.2 Bar Recommended Replacement Differential Pressure: 2.4 Bar Material: Pure Polypropylene Microfibers String Wound Filter Description: This string wound water filter is constructed from precision-wound polypropylene microfiber thread around a porous polypropylene core, forming a thin, dense honeycomb structure. It effectively removes suspended solids, particles, rust, and other contaminants from water, providing excellent filtration performance. Key Features: High filtration accuracy, low pressure difference, high flow rate, high pollution capacity, and long service life. The pore size is smaller on the inside and larger on the outside, enabling efficient depth filtration. The filter media can withstand high filtration pressures. The wire-wound water filter effectively removes suspended matter and particulates from water.
