INOCO High reliability factory manufactured auto backflush filter

INOCO XF-F series automatic backwashing filter provides fully automatic backwashing clean operations, and it can continuously separate impurities from water and other liquid. The maintenance and operation of filter is very simple, even in the severe operation conditions it also can continue to keep running in a good operation.

This filter is a kind of filter which can provide a wide range of comprehensive use of industry, it can guarantee the purity and reliability of filtrated liquid.

Also XF-F series filter can be equipped with different amount of elements to provide maximum filtering area in each filter housing in order to have smallest pressure loss while working.

The pressure design of filter body is usually based on the chemical pipeline filter and steel pressure vessel design standards. The filter also can adapt to the special requirements of other design criteria. Filter main body has the material such as carbon steel, stainless steel, and duplex phase and etc. at the same time, we also can provide special materials such as titanium, pure nickel and etc.

Fully automatic self cleaning

Simple, reliable and economic

Super high flowrate

Rigid filter element and variety options

 The water which needs to be filtered flows into the shell through the lower bottom of the filter and enters the lumen of the filter elements through the rotary table from bottom to top and be drained out through the filter elements. The filtered clean water flows out from the upper outlet of the filter. Solid impurities are trapped in the inner side of filter elements. While in the process of backwashing, no need of cutting off the water. Motor drives filter wheel rotating and the drain valve was opened at the same time. Each filter elements will be backwashed by the filtered clean water in turns.

The pressure difference between the water pressure in the filter and the atmospheric pressure can make filtration liquid flows reversely so that the intercept impurity on inner face of the filter element can be removed. After the wheel rotates a round, backwashing process is over. When backwashing valve closed and drive motor stops.  

YNTSH-XF-F1 Conical elements

XF-F1 series filter element cleverly used the traditional wedge wire filter elements to design innovation cone filter element,filter element has material of stainless steel dual phase steel and alloy steel and etc,wedge gap filter element can effectively filter the fluid with less sticky material ,and can also be applied to coarse filtration field.

Wedge wire filter element'saperture is from 25 micron to 1000 micron and some long life components can be used for more than 20 years in the filter.

YNTSH-XF-F2 Well-shrink type element

When the filter condition is difficult ,INOCO recommends the swell -shrink element type filter.

we have successfully conducted field test to show the sewage filtering capability of swell-shrink element filtering ,INOCO XF-F2 filter can filter sewage into daily-using recycle water.

YNTSH-XF-F3 common type elements

INOCO wedge type cartridge has high strength and precision, as well as flexible design, make it easily be applied to various kinds of complex and special working conditions.

YNTSH-XF-F4 Multi-layers mesh cartridges

F4 series sucking backwash filter is used of multi-layers mesh as elements structure so that filters has the features of maximum filtering area and high backwashing efficiency .combined with INOCO unique laser welding technology ,this series filter is special suitable for offshore platform and marine ship application.

Filter is not only designed to meet the normal flow rate, but also have a set of additional spare filter cartridges ,when it needs washing ,then the spare filter starts working ,so that this does not affect the pipe resistance. the cleaning components move in sucking up and down ,it can clean impurities in shortest time with maximize clean level. The axis of rotation and filter disc pads is made of four fluorine material, and according to the wear and tear condition, it has automatic adjustment function to minimize sliding sideways.

sand filter Products Specification   

Medium filter is usually called depth filters, water flows through a certain thickness, media layer with a certain particles size, then reached the filtering effect .The media may be quartz sand ,gravel or granular materials. filtration level depends on the particles diameter and flow speed through filter bed. INOCO provides a series of various forms of such productsand accessories, can also provide control system for using single or multiple parallel situation, INOCO is willing to offer you the products design ,perfect system and help you select filter media such as sand ,quartz sand ,activated carbon and multilayer media.

sand filter Working principle

Water flows into the filter inlet then through filter layer,suspended impurity in water will be adsorpted by filtering layer,filtered water from filtering cap flows to outlet,cleaning can be done by backwashing ,the flow is the reverse flow from water filtering cap upward,causing filter layer turbulent ,meanwhile the adsorbed impurity are released and discharged from drain valve,backwashing process is completed automatically by pressure differential or timing.

 The dual media filter technical parameters:

Max working pressure:6.5 bar

Testing pressure:10 bar

Max working temperature:60 degree Celsius

Self-cleaning filter Products Specifications

XF series self-cleaning filter is suitable for filters with 1’’-36’’ pipeline to choose from, with advantages of continuously fluid flow, safety operation simple maintenance, XF series self –cleaning filter is widely used in all industry area.

How it works for XF-X brush automatic self cleaning filter

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.

XF-S scraper automatic self cleaning filter

XS-S series scraper filter is self-cleaning by INOCO,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.

Working principle for XF-S scraper automatic self cleaning filter

INOCO 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).
