DFXH series self-cleaning filter (DFXH Filter for short), is the high efficiency self-cleaning filter independently developed by HANK. Removing the impurities particles on the filter element outside by mechanical scraping, it continuously filters on-line.DFXH filter is designed for fine and accurate filtration ranging from 50-500micron. It can avoid extruding and breaking the impurities and is capable of the filtration for water and liquids of viscosity up to 800000cps. DFXH filter is designed and manufactured per HANK’s high performance, high quality and high reliability standard. It is a world-class quality filter.
The conventional filters get clogged frequently when filtering the viscous liquid and removing the soft impurities. The customers have to select larger filters and clean the filter manually and frequently, which means expensive investment, hard work, valuable liquid loss. DFXH filter solves these kinds of problems by its advanced self-cleaning. It always keeps the filter element clean, discharges waste liquid with high impurity concentration, reduces the liquid loss. When filtering the viscous liquids such as dirty water, adhesives, resins, polymers and oil, DFXH filter works more efficiently. DFXH filter is taking place fo vibrating screen, bag filter, basket filter and some kind of back-flushing filter by its technical advantages and low running cost.
