My Irrigation Automatic Disc Filter System adopts the modular design, it well meets various market demands of different flow volumes by providing T-type backwash modules. Going with 2",3" or 4" hydraulic backwash valve as well as a built-in computer chip for automatic scheduling work, it works as an automatic unattended water filtration system, which ensures continuous water supply while discharging the sewage. Flow rate range: 20mï/h to 280 mï/h Filtering accuracy: 130micron. With the Unique Disc and Vortex Structure design, the filter will generate a centrifuge spiral flow of water, which moves away the solid particles in the water. The solid particles will be collected to the top of the disc element with rotational flow. The vortex disc filter system ensures High-Efficient Filtering and water-saving for the low frequency of backflushing.
