CAF900 Electric Water Filter



Process principle of the automatic self-cleaning filter (b)


Water enters into the entrance. Firstly, the primary strainer filters out the larger particles of impurities, and then reaches the fine strainer. In the process of filtering, fine strainer gradually accumulates impurity in the water and forms a filter impurities layer. Due to the accumulation of impurities layer inside, the two sides of the fine strainer form a pressure gradient. When the pressure gradient reaches the default value, self-cleaning will begin. During this time, the clean water continuously supplies, cleaning valve opens, the pressure within the clean room and sewage-absorption decline at large amplitude, through pressure gradient between the filter cartridge and the sewage pipe, sewage pipe and cleaning room form suction through the suction nozzle, thus complete a suction sewage process. At the same time, power motor driven absorption sewage pipe rotates along the axial. Sewage suction machine’s axial movement and rotation during the entire filter clean the surface completely. The entire washing process takes several seconds. Sewage valve closes after the washing. Filter prepares for the next wash cycle.
