Product Description

it is a kind of filter suitable for bad environment, it can be equipped with 3500 microns - 50 micron mesh 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 , usually the default value of pressure difference switch is 0.5 bar (7 psi).
XF-X 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-X series self cleaning filter is widely used in all industries area.


Filter working principle

When the differential pressure of inlet and outlet reaches the preset value, the filter will start the cleaning process. The whole self-cleaning process contains two steps: the drain valve on the end cover of the filter opens; the two stainless steel brushes in ontology mesh is driven by motor inside, then the impurities which is captured by mesh will be brushed by the steel brush and will be discharged from the drain valve. The whole cleaning process takes about 15 to 60 seconds, During this time, the filtration system does not stop and the whole operation process is completed by a control box.


Features and advantages

Continuously water supply: the cleaning process needs little water, which is nearly 5% of filter water yield, the flushing time is 2 ~ 15 seconds, the system uninterrupted water supply.
High filtration precision: the filtering precision can reach 20 microns, there are all kinds of precision filter meshes which can be chosen.
Large filtering area: the effective filtering area of standard filter screen is 7 ~ 40 times of the inlet area.Reliable cleaning types: there are many kinds of control mode: manual, differential pressure, timing, PLC program logic control and other control mode for choices.
Simple and economy installation: diversified structure, suitable for installation in all kinds of site conditions, and does not affect the running effect.
Long service life: Normally the working life will be more than 10 years, according to the requirements, the stainless steel mesh can be easily replaced by different specifications.
