Product Description
RUNLAN DFA Series swimming pool filter portable
Brief Introduction
DFA series swimming pool filter portable , is the new high performance scraping self-cleaning filter independantly developed by RUNLAN. It automatically removes the particles and impurities from the filter element internal surface by mechanical scraping and it can continuously work on-line. DFA swimming pool filter portable 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 swimming pool filter portable is designed and manufactured by following RUNLAN'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 swimming pool filter portable 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 swimming pool filter portable works more efficiently. DFA swimming pool filter portable 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.
Self-cleaning Principle
[ Filtering Status ]
Liquid enters the filter from the inlet. The spring-loaded disc-shape scraper tightly fits the filter element internal surface and stops at the top of the filter element. The liquid passes the scraper and flows across the filter element from inside to outside. The impurities are blocked on the inner element surface. The liquid flows out from the outlet. After running for a period, more and more impurities accumulate and the pressure drop increases. Clean the filter element by the preset differential pressure or the preset time cycle.
[ Cleaning Status ]
The cylinder drives the scraper moving up and down and cleaning the filter element. When the scraper moving down, the impurities are pushed down to the filter bottom, and gravity particles settle down to the impurity collection chamber. When the scraper moving up, the remaining impurities are pushed to the top of the filter element and then flushed off by the liquid. The impurities pass the scraper, get back the filter element internal surface and then scraped off when the scraper moving down. Each cleaning cycle consists of several strokes. After cleaning, the filter element are regenerated. When cleaning, it filters normally and flowrate is not interrupted.
[ Purging Status ]
After several cleaning cycles, the impurities accumulate more and more. Open the valve periodically and purge the waste liquid of high impurity concentration, which can be recovered if necessary.
