Operation:

The flushing valve opens and pressure in the flushing chamber and the dirt collector is significantly lowered resulting in a suction process via the suction nozzles to the dirt collector and from there through the flushing valve discharge. The electric motor simultaneously rotates the dirt collector and moves it along its axis. The combination of the vertical movement and rotation guarantees that the suction nozzles will cover the entire internal screen surface, efficiently cleaning the screen. The whole process takes 15 seconds. During the whole process water supply is uninterrupted.
