Fresno Flow Guard Galvanized Filter, 8", 1200 GPM, 3/32" Screen, Flange Inlet, Flange Outlet (P3821-22)

The P3821-22 is a heavy-duty galvanized inline filter designed to protect pumps, meters, valves, and drip irrigation systems from debris, sediment, and particulate contamination in agricultural water supplies. Rated at 1,200 GPM, it handles high-flow mainline applications with ease. The 3/32" screen catches sand, grit, and organic debris before it reaches sensitive downstream equipment — extending the life of your entire system. Flanged inlet and outlet connections provide a secure, leak-free fit on standard 8" flanged pipe.
