Self Cleaning Filters — operating principle The filtered liquid passes from the inside to the outside of the cartridge, leaving the filtered deposit on the internal surface. This creates a pressure differential. On reaching a preset pressure differential level, the automatic filter cartridge cleaning cycle commences. The gear reduction unit rotates the scraper blades, removing the media, which is discharged through the discharge valve.
The filter cleaning operation functions as the unit continues its filter operation, giving the benefit of no down time.
