The Y-shaped electric brush self-cleaning filter is a fully automatic self-cleaning filter suitable for harsh environments. It can be equipped with a filter screen of 3500-50 microns and a diameter of DN25-DN1000 for different usage requirements. The self-cleaning process of the filter is initiated by a differential pressure switch that constantly monitors the pressure difference between the inlet and outlet of the filter. Typically, the preset value of the differential pressure switch is 0.5 bar (7 psi).
