The iSpring WSP100B spin-down sediment filter with scraper is an ideal safe-guard prefiltration system. It filters out particulate, impurities, sediment, rust, floating objects and other pollutants in water. Serving as a central water purification pre-filter, the iSpring WSP100B protects terminal equipment and appliances such as downstream pipelines, water purifiers, water heaters, wall-hung boilers, dishwasher, washing machines, and shower heads.To fit different plumbing sizes, the unit comes with two types of threads on both ends: 1 inch FNPT and 3/4 inch NPT. Install the system in a dry indoor environment away from heat sources. Ideally, pair WSP50B with iSpring Whole House Water Filtration Systems, such as the WGB21B/WGB12B/WGB32B series, and iSpring UV Water Filter(UVF55) for the increased benefits of a complete set of iSpring POE(Point of Entry) water filtration solutions.
