When the differential pressure of inlet and outlet reaches the preset value, the filter will start the cleaning process. The whole self-cleaning process contains two steps: the drain valve on the end cover of the filter opens; the two stainless steel brushes in ontology mesh is driven by motor inside, then the impurities which is captured by mesh will be brushed by the steel brush and will be discharged from the drain valve. The whole cleaning process takes about 15 to 60 seconds, During this time, the filtration system does not stop and the whole operation process is completed by a control box.

Continuously water supply: the cleaning process needs little water, which is nearly 5% of filter water yield, the flushing time is 2 ~ 15 seconds, the system uninterrupted water supply. 
High filtration precision: the filtering precision can reach 20 microns, there are all kinds of precision filter meshes which can be chosen. 
Large filtering area: the effective filtering area of standard filter screen is 7 ~ 40 times of the inlet area.
Reliable cleaning types: there are many kinds of control mode: manual, differential pressure, timing, PLC program logic control and other control mode for choices. 
Simple and economy installation: diversified structure, suitable for installation in all kinds of site conditions, and does not affect the running effect.
