Industrial water filter

DF is the leading industrial filter manufacturer and exporter in China. With global 18000 enterprises service experience, filtration laboratory, and strong manufacture capability we can provide superior reliability and high performance products for you.

Below is the detail model selection for industrial water filter

1.Automatic type for industrial water filter : cylinder Scraper automatic self cleaning filter

Products specification:

DF series scraper filter is self-cleaning by DF,this new generation of mechanical self-cleaning filter has reached the world advanced technology level,Different with backwashing self-cleaning water filter,scraper filter is not only used for water filtration,but also widely used in the self-cleaning filtering of solvents,acid alkali,polymer,coating adhesive materials and so on,it has higher efficiency and precision of range 30-1500 microns,it can filter liquid viscosity up to 800000 centipoises,and also be applied in water treatment,petrochemical,metallurgy,electric power,chemical,paint,printing,ink,paper,food and beverage,pharmeceutical,metal processing industrial and etc.

How it works:

DF mechanical cleaning filtration principle is very simple, We install stainless steel screen (2)on a cylindrical shell(1). When unfiltered liquid l flows into the shell from the inlet(3), solid impurities are leached and deposited on the inner surface of the screen .filtered liquid flows out from the outlet(4), when filter screen need cleaning (depending on the time &pressure differential)A clean dish(5) tightened with spring scraper the mesh inside surface back and forth constantly and removes the deposition of solid impurity, when the debris is separated from gap of the filter screen, washing dish will discharge the dirt into bottom of the shell(6) then drain through the flow channel(7).

2.Automatic type for industrial water filter: Brush automatic self cleaning filter

Products specification:

DF series automatic self-cleaning filters is a kind of filter suitable for bad environment, it can be equipped with 3500 microns - 50 micron filter screen and 8-36 "pipeline diameter for different using requirements. The cleaning process is started by a differential pressure switch which is monitoring the different pressure of inlet and outlet pipeline of filter, usually the default value of press difference switch is 0.5 bar (7 psi).

How it works:

When the differential pressure of inlet and outlet pipeline reaches the presented value, the filter will start the cleaning process. The whole self-cleaning process contains two steps: the drain valve opens; the two stainless steel brushes which is driven by motor inside will brush off impurities which was captured by the mesh and then impurity will be discharged from drain valve.. The whole cleaning process takes about 15 to 60 seconds, while during this time, the filtration system does not stop flowing and controlled by a control box.

3.Manual type for industrial water filter:Sucking automatic self cleaning filter:

DF series self-cleaning filter has higher filtration precision and minimum cleaning water loss,it can provide the most security for industrial system.

How it works:

When the pressure differential inside and outside of filter mesh reaches the set default value or when the timing cleaning switch reaches the set time, then system starts the cleaning process.

4.Manual type for industrial water filter: Cartridges filter

Products specification:

Cartridge filters are effective in the removal of moderate amounts of particles from liquids in the size range of 50 to 0.035microns. When filtering large amounts of solids at high flow rates, other treatment methods such as self-cleaning multimedia filters may be required aspre-filters, followed by cartridge filtration, if needed.The most popular micron sizes are the 5-micron general-purpose filter cartridge, and 0.2 submicron“Absolute” pleated filter cartridge for final filtration on high purity water systems.

Technical parameters:

Filter medium: water, chemicals, water, air, nitrogen, oxygen, hydrogen, and so on

Volume: standard model with 12-300pcs pleated membrane filter, filter length for 10, 20, 30 and 40

Filtering flow rate: 0.1 ~ 500 m3 / H; reference to water

Body housing material: CS, 304, 304 l, 316, 316 l, C276, 316, coating

Micron rating: 0.003 micron to 50 microns

Working pressure: 0-2.5 Mpa

Working temperature: 0-260 ℃

5.Manual type for industrial water filter: Pipe line filter

Products specification:

Pipeline strainers are sometimes used in double arrangements so that flow can be diverted while the system remains in service and the screen is cleaned. This can be accomplished with a duplex style strainer up to 8" diameters, but can also use a second strainer placed in parallel with the primary strainer.

Model selection:

6.Manual type for industrial water filter: bag filter &multiple bags filter

DF bag filter has been widely used in the industry and become a standard. Customers can choose single bag filter or multi bag filter system to meet different applications according to DF standard.

INOCO multiple bag filter can provide 1-40 bags for options.

Diversified and advanced filter design, precision filter bags and automatic combination DF provides the best solutions for you.
