    Working Principle

    Auto Backwash Filter Working Principle:Water enters from the inlet, passes through the coarse filter screen to filter out larger particles of impurities, and then reaches the fine filter screen.
    The fine filter screen gradually accumulates dirt and impurities in the water to form a filter impurity layer during the filtration process. Because the impurity layer is accumulated on the inside of the fine filter screen, a pressure difference is formed between the inner and outer sides of the fine filter screen.
    When the pressure difference of the filter reaches the preset value, the automatic cleaning process will start. During this time, the clean water supply is continuously flowing, the cleaning valve is opened, and the water pressure in the cleaning chamber and the sewage suction device drops significantly, passing through the filter cartridge and the sewage suction pipe.
    Due to the pressure difference, a suction force is generated between the suction pipe and the cleaning chamber through the suction nozzle, forming a dirt suction process. Simultaneously, the electric motor drives the suction pipe to make a spiral movement in the axial direction.
    The combination of axial movement and rotary movement of the dirt sucker completely cleans the entire inner surface of the filter.
    The entire flushing process only takes tens of seconds. The drain valve is closed at the end of the cleaning. The filter is ready for the next flush cycle.
