DFX Mechanical Self-Scraping Filter (External Rotary SS Blades)

DFX series automatic mechanical scraping filter is the high efficient self-cleaning filter independently developed by LIVIC.

DFX filter is designed and manufactured per LIVIC’s high performance and high reliability standard with world class quality. DFX filter is designed for fine filtration ranging from 50-500 micron and is capable of filtrating in high viscosity fluids up to 800000 cps. Removing the impurities particles on the filter element outside by mechanical scraping can avoid extruding and breaking the impurities.

DFX's self-cleaning function keeps the filter element/screen clean. It is triggered by differential pressure or timing, whichever comes first. To reduce the liquid loss during purging, high impurity concentration waste liquid will be discharged. Instead of vibrating screen, bag filter, basket filter and other kinds of back-flushing filter, DFX filter works more effectively and efficiently in high viscous liquids such as dirty water, adhesives, resins, polymers and oil.
