Y-Filters are used to protect drip emitters, dripperline, sprayers, bubblers and misters from sand, silt and other impurities that may clog them over time. Filters are typically installed between the vacuum breaker and pressure regulator. Proper water filtration is essential for the efficient operation of drip micro-irrigation systems. Filters are available with 3/4″ or 1″ MIPT inlet/outlet and also available with 3/4″ FHT swivel by 3/4″ MHT inlet/outlet. Y-filters come with either a 150 mesh polyester or stainless steel screen. Bottom of filter has a cap or valve for easy flushing.
