CDFS Helical Scaning Auto Self-cleaning Horizontal Water Filters

Product structure

Principle descriptions

    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 pressure differential increases to the pre-determined level, the flushing cycle starts.  A automatic valve is opened on the drainage outlet then electric motor activate suck scanner system which generates an helical movement along the screen to vacuum up the captures particles from the screen.  The captured 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.

Technical parameters

Product selecting

When you are choosing automatic screen filters, please consider the following parameters:

   1. Flow capacity( Pipe diameter)

   2. Filtration range

   3. Shell material

   4. Pipeline pressure 

   5. Chemical properties of the filter medium 

   6. Suspended solids(SS) concentration of filter medium

Installation and connection 

please keep the drain valve’s outlet direction horizontal position or down position to ensure the sewage is discharged completely.(More filters in parallel could get bigger flow)
