How it works:

   The liquid to be filtered through the inlet flange reaches the bottom of the filter chamber, about 50% of the liquid through the central tube is straight vertical guide to the top of the filter chamber, and then flows down the open end of the filter element, another 50% from the bottom of the filter element the opening into the filter of the filtered liquid flows out through the gap of the filter, filtering precision of 50μm.

   When the impurities trapped in the filter needs to be cleaned, the backwash system automatically starts a filter located at the top of the rotation arm cover began to turn driven by the motor; Meanwhile, rinse the bottom of the rotation arm, under the corresponding filter in beginning slag valve open position the backwash cycle, the filter element under the control of the rotating wash arm and the top arm is cleaned one by one without interruption of the filtration step, washing liquid into the filter, forming a top-down flow, which can effectively prevent the upper filter clogging, when the inlet and outlet reaches the set pressure or reach interval set by the program, backwash system will prompt start.
