Filtering process

Water is filtered through the coarse screen of the filter, where there is a gradual build-up of dirt on the fine screen.This build-up causes a gradual increase in pressure differential between the inside and outside of the screen. When the pressure drop reaches a pre-set level, the cleaning cycle commences.

Self-cleaning process:

The M300 self cleaning process begins when the rinse controller activates the hydraulic valves and piston, and water from the hydraulic motor chamber flows out.

Pressure inside the hydraulic motor chamber, the dirt collector, and the suction nozzles drops to a very low level creating a pressure gradient between the reverse side of the screen (clean water) and the inside of the screen (dirty water), opposite the suction nozzles.

This back-flushing operation cleans the screen ahead of the suction nozzle. The water and the dirt passing through the hydraulic motor cause the collector to rotate, while the piston is activated in an axial movement.

The combination of the axial and rotational movement of the nozzles means that the entire area of the fine screen is totally cleaned.

As dirt on the fine screen is washed out, the pressure gradient disappears, the rinse controller unit closes the hydraulic valves, and the piston moves back to its original position. The system is now ready for the next rinsing cycle.
