Mechanically Cleaned Scraping Self Cleaning Filter, DFA Series for
Polymer and Coatings
Description
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.
Sealing Material
Available O-ring seal materials for housing and filter element:
NBR,EPDM,VITON,silastic,FEP encapsulated silastic, which meet
filtration demands for various neutral liquids, acids, alklis,
solvent, etc.
Available Seal material for piston rod: NBR,PU(Polyurethane),VITON. |  |
Applications:
■ Applicable Industries: petro-chemical, fine chemical, pulp and
paper, food and beverage, water treatment, etc.
■ Applicable Liquid Types: wax, coal oil, monomer, polymer, citric
acid, fermented broth, cosmetics, silicon solution, soap, sorbitol,
steriodsugar, wet end additives, adhesives, inks, lubricating oils,
coatings, resin, rubber, ethanol, miscella, edible oil, juice,
diesel, etc.
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
