This 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 conditions. 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, long service life, non-toxic, tasteless, and ensures 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 Pure Polypropylene Microfibers: This string wound filter is made using precision winding technology, where microfibers are tightly wound around a porous polypropylene core. The fine, dense structure effectively removes suspended solids, particles, rust, and other contaminants from water, providing excellent filtration performance. High Filtration Accuracy: The pore size is smaller on the inside and larger on the outside, enabling superior depth filtration. The wound construction can withstand high filtration pressures. Effectively removes suspended matter and fine particles from water.
