Mechanical Scraping Self Cleaning Filter, Trap Iron Exchange Resin Filter
DFA series pneumatic scraping self-cleaning filter ( DFA FILTER for short), is the new high performance scraping self-cleaning filter independantly developed by LIVIC. It automatically removes the particles and impurities from the filter element internal surface by mechanical scraping and it can continuously work on-line. DFA is designed for filtration of high viscosity up to 800,000mPa.s. The filtration degree ranges from 50~1500μm. It can scrape the impurities off the filter element surface most quickly, which makes it more efficiently removing the impurities. It is applicable for water and various viscous liquid. The DFA filter is designed and manufactured by following LIVIC'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 or clean the filter manually and freqeuntly, which means expensive investment, hard work, valuable liquid loss. DFA filter solves these kinds of problems by its advanced self-cleaning principle. 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 oils, DFA filter works more efficiently. DFA filter is taking place of the vibrating screen, bag filter, basket filter and some kind of back-flushing filter by its technical advantages and low running cost.

TECHNICAL FEATURES AND ADVANTAGES
■Up-and-down reciprocating scraping, scrape impurities off directly, especially good at viscous liquid filtration and removing viscous suspending impurities
■Simple structure, easy disassembly, pull the filter element out easily after removing the scraper, easy for internal cleaning
■Automatic operation, continuously on-line filtration, terminate the hard work of filter element replacement and cleaning
■No disposable filter media, save the cost of filter media consumption and the environment treatment
■Very low filtration pressure drop, steady flow rate, save the energy, good for keeping the process continuous and steady
■Closed filtration, prevent danger of liquid leakage, good for safety production and operator’s health
