[NSF/ANSI 372 Certified] The WSP50ARJ sediment water filter is certified lead-free under NSF/ANSI 372 standards, ensuring safer and cleaner water for your home.[Jumbo Size and High Flow Rate] Designed for a more complicated well water situation, the WSP50ARJ spin-down sediment water filter provides a 1-gallon capacity, which is 22 times larger than sediment filters. The maximum flow rate of WSP50ARJ is 25 GPM. Universal fittings can be easily installed and adaptable to other applications"”two types of threads on both ends of connectors: 1-inch MNPT and 3/4-inch FNPT.[Advanced Frontier Water Filter] The whole house sediment filter uses a 50-micron filter screen. This means it can filter up to 99% of large particulates such as sediments, dirt, rust, sand, floating objects, and other water pollutants. As a central water purification pre-filter, WSP50ARJ is a reliable first line of defense that can protect terminal equipment and appliances, including downstream pipelines, water purifiers, water heaters, wall-hung boilers, washing machines, and showerheads.[Auto Flushing Module] iSpring WSP50ARJ whole house water filter has an integrated auto flushing module (dual power supply) that saves time and effort on routine maintenance. Choose from auto, semi-auto, and manual on the HD touch screen to enable the system to automatically flush on a preset schedule.[Flushable and Reusable] The whole house spin-down sediment water filter is used to create a multi-layer gradient filtration system, removing considerable workload from the more advanced filters that follow it; this results in longer filter life. Regularly flushing can prolong the filter''s lifespan, reduce the need to replace it, and save money.[Pressure-resistant and Durable materials] 316L food-grade stainless steel precision filter mesh, explosion-proof transparent housing provides clear visibility, great intuitiveness, and convenience. The explosion-proof test is over 500 psi pressure, and the water hammer tests are passed over 100,000 times.
