DFX Series mechanical cleaned filters       

DFX series mechanical cleaned filters (DFX Filter for short), is the high efficiency scraping self-cleaning filter independently developed by RUNLAN. Removing the impurities particles on the filter element outside by mechanical scraping, it continuously filters on-line. DFX filter is designed for fine and accurate filtration ranging from 50-500 micron. It can avoids extruding and breaking the impurities and is capable of the filtration for water and liquids of viscosity up to 800000cps. DFX filter is designed and manufactured per RUNLAN's high performance, high quality and high reliability standard. It is a world-class quality filter.

RUNLAN is the world leading self-cleaning filter manufacturer with its complete series scraping self-cleaning filters, which has three sub-series: DFX series, motor-driven external scraping; DFA pneumatic-driven internal scraping; DFM motor-driven internal scraping. They are good at different applcations and meet the various mechanical self-cleaning needs.

WORKING PRINCIPLE

The liquid enters the filter from the inlet(1), flows through the filter element(6) from outside to inside. The filter element bottom is connected to the outlet(2), through which the liquid flows out. After the filter element captures the impurities, the cleaning action is trigger by the preset time or differential pressure value. The gear motor(4) drives the scraping blades(7) to rotate and remove the impurities on the filter element outside surface. The impurities moves off along the blades and falls down to the filter bottom. The rotating plates push the gravity impurities into the collection chamber(5). The impurities are collected at the filter bottom and in the collection chamber. The discharging valve open per the preset time and discharging the waste liquid with high impurity concentration through the drain outlet(3), the purged liquid can be reclaimed if necessary.

TECHNICAL FEATURES AND ADVANTAGES

1. Automatic 24-hour on-line filtration, no frequent changing out and cleaning 

2. No disposable filter media comsuption, save filter media cost and environment cost

3. Stainless steel scraping blade, good impurity removing performance 

4. Top quality V-SLOT filter element, accurate slots, extreamly smooth, easy to scrap

5. Very low pressure drop, stable flowrate, save energy comsuption

6.back-flushing function can be added to help clean the filter element

7. Close filtration, no dangerout liquid leakage, good for safe production

8. Discharge waste liquid with high impurity concentration, avoid valuable liquid loss

9. Various modular combination and automation modes available, meet different filtration needs

10. Equiped with world-famous gear motor, high reliablity and long service life 

11. Assitant lifting device , only one operator can open and close the filter cover
