This filter is installed between the irrigation valve and drip regulator to protect drip emitters from rust, sand and other impurities that may clog them Useful Y-filter controls debris Heavy duty plastic with maximum UV & oxidizer protection easily removed for cleaning by unscrewing the threaded cap Need to use the filter Irrigation method:Sprinkler irrigation: field, lawnMicro-sprinkler irrigation: economic crop, fruit trees, vegetableDrip irrigation: greenhouse, economic crop, fruit treesworking principle:The filter core is shaped by many plastic discs stacked together. The plastic discs are with grooves on the surface, discs surface with a radially reduced groove, when the upper and lower discs stacked, the formation of a number of small cross-flow channel. When water flow into the channel, large impurities in the water are filtered at the various channels, which is discs surface.The depth and number of grooves on the disc determines the size of the filtered impurities. This product filters impurities about 120 mesh.Product Features:1.Made of engineering plastic, high mechanical properties, strong corrosion resistance and abrasion resistance.2. Apply to kinds of water, accuracy filtration, filter sand and mud effectively. 3.Pressure loss is small, normal pressure loss is 0.1-0.5 bar 4.The injection molded parts are easy to replace and match, are stable and easy to maintain. Almost no need routine maintenance, no need professional tools5.Long life, easy to clear, install, take apart, transport6.Easy to backwashing, high efficiency, water consumption rate no more than 0.5%Specification:Material: plasticColor: blackType 1 Connection : Male thread 1.25''Type 1 Flow: 14m3/ hType 2 Connection : Male thread 1.5''Type 2 Flow: 15m3/ hType 3 Connection : Male thread 2''Type 3 Flow: 25m3/ hWorking pressure: 1-8kgPackage included:1 pcNotice: The size is measured by hands, please allow minor error of measurement.
