Working principle
The Self-Cleaning Process
During the self-cleaning process, filtered process water continues to flow. The Exhaust Valve open and the Drive Unit rotates two stainless steel brushes that sweep the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the brushes and flushed out the exhaust valve.
Once the cleaning cycle is initiated the exhaust valve opened and a suction scanner is activated. The driving mechanism then rotates the patented suction scanner in a slow fixed rotation while simultaneously moving the scanner linearly. The exhaust valve causes a high-velocity suction stream at the nozzle tip, which cleans the inner surface as the suction scanner spirals across the screen. The downstream flow is uninterrupted during the cycle, which is completed in 20-40 seconds.
