What is DFX filter housing？

Full automatic filter housing system”

Full automatic outside scraper filter housing DFX series;

DFX series self-cleaning filter housing (DFX filter for short) is of sffiltech’s independent research and development of efficient scraper type self-cleaning filter. By using mechanical scraping to automatically cleaning particle impurity of outer surface of filter element to ensure continuous on-line filtration.

DFX filter housing is mainly used for high precision filter, precision range 50-500 microns. It’s able to the maximum extent to avoid crushing the impurities, thus efficiently removing all of more impurities, suitable for high viscosity liquid filtration. Viscosity up to 800000 CPS.

DFX filter follows the sffiltech’s high performance, high quality, high reliability design and manufacturing standards are of the international first-class quality. sffiltech is one of the world's leading manufacturer of self-cleaning filter . It has a full series of scraper type self-cleaning filter products, three sub series, applicable to different occasions, to fully meet the industrial customer’s variety of mechanical self-cleaning filtration requirements.

woring principle of DFX filter housing

Liquid inflow from filter inlet and from the filter element of outer surface flows past the filter element lower end connection outlet. Liquid outflow from the outlet .When the surface of the filter element is blocked to a certain amount of impurities, to perform the cleaning procedure at definite time or by setting the pressure difference.

Gear motor drive slicker to erase impurities of outer surface of the filter element, impurities along the scraper leave the surface of the filter element. With the downward liquid falling to the bottom of the filter, the rotating sweep board sweeps the bottom impurity into the dirt collecting chamber. Impurities accumulate in collecting cavity and bottom of the filter, sewage valve timing automatically open, the liquid with high concentration of impurities is discharged from the discharge port. Residual liquid can be recovered or directly discharged.

Technical features and advantages

1) Full automatic operation, 24 hours of continuous online filtering, ends heavy filter element replacement and cleaning work;

2) Low cost of material and high environmental protection with no disposable supplies.

3) Using metal sheet scraper has excellent effect. Impurity removal ability was significantly improved and avoided crushing impurities.

4) Top quality V-SLOT filter element, gap precision, extreme smooth surface, easy to scrape, high strength, long service life.

5) The filter pressure loss is very small, the flow is stable, energy saving, and the conducive to stable techniques.

6) Can be added to the back washing function as auxiliary cleaning filter element.

7) Closed filtration, to prevent the leakage of hazardous materials, to ensure safe procedure.

8) High concentration of waste liquid can be recycled, to avoid the loss of high value materials.

9) A variety of module combination and automatic mode to meet the requirements of various filtration systems.

10) The standard of international famous brand geared motor, high reliability, long service life.

11) Standard feature of having the auxiliary cover lifting device, one person can operate easily.
