Automatic Self Cleaning Filter for Liquid Purification Rain Water Filter

• The whole process is as below:
  The liquid to be filtered flows into the filter through the inlet, then flows form inside to outside of the filter mesh, the impurities are intercepted on the inner of the mesh. 
  When the pressure difference between inlet and outlet of the filter reaches the set value or the timer reaches the set time, the differential pressure controller sends a signal to motor to rotate the brush/scraper for cleaning, and the drain valve opens at the same time. The impurity particles on the filter mesh are brushed by the rotating brush/scraper, then discharged from the drain outlet.
