Pistonless models M100-750 , M100-1500
Filtering process:
Water is filtered through the fine screen To the outlet. The filtration
cake is accumulated on the inner surface of the fine screen
causing pressure differential To build up.
Self-cleaning process:
The M100 pistonless filters will start the self-cleaning process
when the pressure differential across the screen reaches
a preset level. The rinse controller opens the flushing valve
creating a strong backflush stream To atmosphere.
This backflush creates a suction effect at the nozzles, cleaning
the face of the fine screen directly in front of the nozzle openings.
Backflush water Then flows through a collector pipe via a
hydraulic rotor To the flushing valve, causing the dirt collector
assembly To spin. Pressure drop in the rotor chamber forces the
collector assembly upward. The combined spin and upward
movements ensure that the suction nozzles sweep the entire
screen area.

When flushing is completed, a second flushing cycle is triggered,
pushing the collector assembly downward To its original position.
The combined flush cycle takes 6 - 10 seconds.

Filtering process:
Water is filtered through the inlet and is pre-filters through the coarse screen and Then filtered through the fine screen. From there it is passed To
the outlet and as filtration cake is accumulated on the inner surface of the fine screen pressure differential builds up.

Self-cleaning process:
The M100 piston filters will start the self-cleaning process when the pressure differential across the screen reaches a preset level. At a preset level,
the rinse controller opens the flushing valve creating a strong backflush stream through the drainage To the atmosphere. This backflush creates
a suction effect at nozzles, cleaning the face of the fine screen directly in front of the nozzle openings.
Backflush water now flows through collector pipe via hydraulic rotor To the flushing valve, causing the dirt collector assembly To spin.
Pressure drop in the rotor assembly and drainage of the piston 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.
