AutoFilt Automatic Back Flushing Filter XF Series Filter for
Cooling Water
Description
XF Series Automatic Back-flushing Filter is a new generation
self-cleaning filtration system independently designed by LIVIC, it
is integrated with a number of slotted filter elements. When the
filter elements are clogged, a specially designed back-flushing arm
will clean the elements one by one. As the high-end self-cleaning
filter, it is especially designed for customers who take good
quality and high eliability into consideration firstly .The XF
filter consists of world-class top quality crucial parts, such as
filter element, gear motor, control system, etc..
Compared with ordinary mesh type self-cleaning filter, XF Series
Automatic Back-flushing Filter has unparallel advantages. It has
rigid and durable V-SLOT filter element, highly uniform slot width,
large filter area in single filter, super high flowrate up to
3000m3/h in single filter, fine filtration at low surface flow
velocity, high reliability. It applies to the filtration of dirty
water containing oil sludge type impurities, soft and viscous
impurities, high content impurities, small amount of hairs and
fibers.
XF Series Automatic Back-flushing Filter, which filtration rating
ranges from 50-2000 micron and its line size is available from 2’’
to 24’’.XF Filter has 3 sub-series: S series, as the large filter
area filter, applies to high flowrate filtration or high precision
filtration; M series, as the small filter area filter, applies to
low flowrate filtration or rough grade filtration; T series are
specially designed for super high flowrate at rough ratings. See
the figure on page 3 to select the right series.
XF Series 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. XF Filter automatically works
continuously on-line and reduces the downtime cost, maintenance
cost and labor cost. XF Series Automatic Back-flushing Filter is
the advanced solution for the self-cleaning filtration of water and
low viscous liquids.
V-SLOT High Performance Precision Filter Element
XF filter adopts V-SLOT precision filter element of the world-class
top quality with following advantages:
■ Filtration rating ranges from 50 to 2000 microns, highly uniform
filtration slots with deviation less than 5 micron
■ High opening rate, higher flow rate in same filter area, higher
dirt holding capacity, more compact structure
■ 316L material, excellent corrosion resistance. SuperDuplex and
Ti2 are available, especially suitable for sea water
■ Smooth inner surface, V-shaped slot, less clogging chance,
excellent back-flushing performance, steady flowrate.
■ Suitable for filtration of inferior liquids containing knotty
impurities such as oli sludge, gel and microfiber.
■ Strenthened structure, no deformation when pressure drop
increasing, stable particle bridging, higher removing effciency
■ High resistance against the forward and reverse pressure,
extremely long service life more than 10 years

Typical Main Pipelined Installation Diagram
Protection Strainer
It is necessary to install the protection strainer before the pump
or XF filter to remove the large particles or impurities like rope
and yarn, which maybe block the filter's moving parts. Usually, XF
filter with ratings 50~600μm should be protected by a 3mm strainer,
while XF filter with ratings 600~2000 should be protected by a 8mm
strainer. LIVIC SF series strainers with line size from 1" to 48",
large filter area and easy operation are the ideal protection
strainer for the XF filter.
