BOCIN-XF-F series automatic suntion backwashing filter is a kind of filter which can provide a wide range of comprehendsive use of industrial ,it can guarantee the purity and reliablity of filtred liquid.
This series can be equipped with different amount of elements to provide maximum filtering area in each filter housing ,this makes the filter to have smallest pressure lose when 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 requirement of other design criteria ,filter main body has the material such as carbon steel ,stainless steel ,and duplex phase steel ,and etc,.at the same time we also can provide special material such as titanium ,pure nickel and etc.

BOCIN-XF-F1 series automatic suntion backwashing filter
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 element 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 the filter elements, no need of cutting off the water flow when on backwashing process, Motor drivers filter wheel rotating and at the same time the drain valve was open, Each filter element will be backwashed by the filtered clean water in turns.
The pressure difference between the water pressure in filter and the atmospheric pressure can make filtration liquid flow reversely so that the intercepted impurity on inner face of the filter element can be removed, After the wheel rotates a round, backwashing process is over, then backwashing valve closed and drive motor stops.
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.
Advanced mesh shape can help stopping the medium which may cause obstruction occurs when using traditional wedge wire components,the filter situation will get better with new advanced mesh shape ,wedge filter element is particularly suitable for the filter with a higher differential pressure filtration ,the size of wedge gap filter element is associated with required filtration precision ,The V shape can be designed to follow the direction of flow ,but also can be against the directionof flow.
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.
BOCIN-XF-F2 series Automatic backflush filter
When the filter condition is difficult ,BOCIN recommends the swell -shrink element type filter.
During the extensive research and development of the non-metallic components,BOCIN design the polypropylene filter element which obtained a patent,this way of filtering is a kind of innocation in technology.we have successfully conducted field test to show the sewage filtering capability of swell-shrink element filtering ,BOCIN XF-F2 filter can filter sewage into daily-using recycle water.swell-shrink element can produce filter seam in backwash process to avoid being stuck by the hard dirt,The solid material which is left in the filtering process is trapped inside of the filter element(As shown in figure I)when the backwash begins,the direction of flow is reversed and flows from the outside to the inside of the components,backwashing expends the space of filter element in a very short period of time(swell-shrink effect)then can clean up the most difficult removing dirt.(As shown in figure 2)
BOCIN-XF-F3 series automatic suntion backwashing filter
Drain size: DN200-DN25
Clean control:pressure differential or timing
Backwash media:liquid after filtering
Min water comsuption(L):10-60

BOCIN-XF-F4 series Automatic backflush filter
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 BOCIN 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.
2, Automatic backflush filter Wedge type elements application:
BOCIN wedge type cartridge has high strenght and precision ,as well as flexible design ,make it easily be applied to various kinds of complex and special working condition.

BOCIN Automatic Back-flushing Filter can remove the solid particles from various water resource and low viscosity liquid (e.g. machining coolant). It makes the fluid meet cleanness requirement and protects downstream key equipments from clogging, abasing and fouling. It increases the key equipment running efficiency and service life. BOCIN Automatic Back-flushing Filter automatically works continuously on-line and reduces the downtime cost, maintenance cost and labor cost. IBOCIN Automatic Back-flushing Filter is the advanced solution for the self-cleaning filtration of water and low viscous liquids.
BOC AC-Backw series are kinds of automatic backwashing self-cleaning filter suitable for demanding environments, for different application requirements ,3500micron -50micron filter screens are available.with 8"-36" inlet/outlet diameter. The self-cleaning filtration is started by a differential pressure switch which is monitoring the pressure difference on the filter inlet and outlet.
Continuity water supply: very less cleaning water requirement ,just 1% of the out water.the flushing time is2-15 seconds, and the whole system is continuity water supply.
High filtration precision: the filtration precision can be up to 20 microns, with a variety of precision filter screens.
Large filtration area: the standard effective filtration area is larger 7 to 40 times than the entrance area.
Reliable cleaning: there are a variety of control modes, such as manual, pressure difference , time, setting and PLC program logic control .
Low-cost and simple installation: various structure forms, suitable for installation various of conditions.
Long service life: more than 10 years ; the filter screen is made of stainless steel, and if necessary, the filter screens of different specifications can easily be replaced.
