Bentonite Scraping Self Cleaning Filter, Mechanically Cleaned Latex Filtration
Description
DFA series pneumatic scraping self-cleaning filter ( DFA FILTER for short), dramatically reduce product loss, require minimal operator intervention and improve flow consistency. The DFA features the fastest cleaning action of the mechanically cleaned family. The DFA Series operates at a consistently low differential pressure and delivers simple, reliable operation in which a low initial investment is a key driving factor.
Considered the most efficient mechanically cleaned filter on the market, the DFA series of mechanically cleaned filters is ideal for highly viscous, abrasive, or sticky liquids. The DFA series mechanically cleaned filters operate at a consistently low differential pressure and deliver simple, reliable operation in which a low initial investment is a key driving factor. 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
