As a larger, upgraded version of WSP series, WSP100B filters out particulate, sediment, rust, and floating objects. WSP series can be used for waste water treatment by spin down the sediment. Flushable and reusable, used to create a multi-layer gradient filtration system taking the considerable workload off finer filters that follow it and result in longer filter life. Built-in filter screen scraper saves time and effort on routine maintenance. Pressure-resistant and durable materials: lead-free brass machine head, food-grade stainless steel mesh filter screen, and explosion-proof transparent housing. Easy installation, no welding or glue needed. Works well with copper, PEX, PVC, and CPVC pipes. The 1” inlet and outlet FNPT fittings provide a maximum flow rate of 25 GPM. Two types of threads on both two ends of connectors: 1-inch MNPT and 3/4-inch FNPT. 30-day money-back guarantee. 1-year manufacturer warranty.
