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
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
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
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.
