DFA SERIES pneumatic scraping self-cleaning filter (DFA FILTER for short), is the new high performance scraping self-cleaning filter independently 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 800000mPa.s. The filtration degree ranges for 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.
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 flowrate, save the energy, good for keeping the process continuous and steady
Closed filtration, prevent danger of liquid leakage,
