Automatic Back Flushing Filter , XF Series Self-cleaning filter for water treatment





XF Series Automatic Back-flushing Filter are automatic filters for industry and technology. They ensure the cleanliness of water, coolants and lubricants as well as lower viscosity fluids. The XF Series filter range is very versatile and diverse and ideally suited for retrofitting in existing plants. XF Series 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.
