Water enters the filter through the inlet(1) and is pre-filtered through the coarse screen(3)
and then is filtered through the fine screen(4). From there it passes to the outlet(2). As dirt
accumulates on inner face of the fine screen,pressure differential builds up. At a preset level,
the rinse controller(12) opens flushing valve(9),creating a strong backflush stream through the
drainage(11) to the atmosphere.This backflush creates a suction at nozzles(6),cleaning the face
of the fine screen directly in front of the nozzle openings.

Backflush water now flows through collector pipe(7) via hydraulic rotor(8) to flushing valve,
causing the dirt collector assembly(7) to spin.Pressure drop in rotor assembly(5) and drainage
of piston(10) forces the collector assembly into axial movement.

The combined spin and axial movements ensure that the suction nozzles sweep the entire
screen area.

When flushing is completed,a second flushing cycle is automatically triggered,pushing the
collector assembly to its original position.The combined flush cycle takes 10-15 seconds.
