Functionality of the self-cleaning filters
+-

Self-cleaning filters operates on the principle of mechanical filtration followed by automated backwashing to remove accumulated particles from the filter element.

Filtration stage

The medium flows through the filter element either from inside to outside or from outside to inside. Here the dirt particles are retained and the cleaned medium reaches the filter outlet. When the differential pressure reaches a certain value, a signal is transmitted from the differential pressure indicator to the control unit, which automatically triggers the backwashing process. The backwashing process may also be initiated by a period of time between flushing, a level in a tank or reservoir connected to the filter or any other convenient parameter. 

Backflushing phase

During backflushing, the dirt particles are flushed off of the filtration surface by filtered fluid reversal of flow (own medium or through external flush medium, compressed air or service water).

Advantages of automatic filters
+-

Continuous Operation: One of the key advantages of automatic filters is their ability to perform continuous filtration without the need for manual intervention. The automated backwashing system ensures that the filter remains operational even during periods of heavy contamination, minimizing downtime and optimizing filtration efficiency.

Hard-to Reach Locations: In areas that were previously considered inaccessible or difficult to maintain, automatic filters are an absolute game changer. 

Connected filters: The central control system allows operators to monitor the status and performance of all connected filters from a single interface. This improves the operational efficiency, the reliability, and the flexibility of the system.

Reduced Maintenance: By automating the backwashing process, the need for manual cleaning or replacement of the filter element is minimized, reducing maintenance requirements and associated downtime.
