Principle of auto self clean water filters

    The water flows through the screen and the particles are retained on the inside of the screen of the filter element. The filtered water then flows out through the outlet.

    When the particles accumulated to a certain number and the pressure differential increases to the pre-determined level, the flushing cycle starts. 

It include two steps: First, the automatic drain valve opens on the drainage outlet. Then, electronic motor drives the cleaning brushes which are inside the screen, the solids are expelled through the drain valve.

    Filters continue to supply filtered water even during the flushing cycle.The whole working system is controlled by a smart box which has several control modes: pressure differential, time, manual and PLC.

Installation and connection 

  •  Please pay attention to prevent the control box, sensors and the transmission parts from damage during the process of installation and use.
  • Please connect the pipes according to the arrows on the filter.And keep the drain valves outlet direction horizontal position or down position to ensure the sewage is discharged completely.
  • In a power system,  filters should be installed between the pump and water-using facility.
  • please install shut-off valves before and after the filters for easy repairing.
