Filtration: wound water filter have a deep bed filtration function,which It presents structure of being dense inside and sparse outside. Wound sediment filter can reduce 99.99% sand, scale, rust, sediment, particles. High Capacity: The filter can filter 20000 - 30000 gallons depending on water . Suggest to replace it 3- 6 months for the average household for optimal performance depending on the use. Multiple Advantages:It has the advantages of high filtration accuracy, rate, small pressure difference, high compressive strength, pollution tolerance, non-toxic and tasteless, and no secondary pollution. Maximum Operating Temperature(Celsius): 80 Celsius Applicable pH value: 1-13 Maximum Operating Differential Pressure(Bar): 4.2Bar Recommended Changed-out Differential Pressure(Bar): 2.4Bar Pure Polypropylene Microfibers String wound filter is a kind of water filter.The textile fiber which made from technology of precision, winding in the porous skeleton (polypropylene) , with thin dense structure, can effectively remove the suspended solids in the fluid, particles, rust and other , has the very good filtering characteristics. Multiple advantages High filtration accuracy, small pressure difference, , pollution capacity and long service life. The filter pore diameter is small inside and outside, with good deep filtration effect. wound can withstand high filtration pressure. The wire-wound water filter can effectively remove suspended matter and fine particles in the water. High capacity The filter can filter 20000 - 30000 gallons depending on water . Suggest to replace it 3- 6 months for the average household for optimal performance depending on the use. colour:white Material:Polypropylene size:Length: 250mm : 10m Outer diameter: 60mm Package Contents: 5 * Water purifier filter Only the above package content, other are not included.
