automatic back-flushing filter ( XF Filter for short) is the new generation self-cleaning filter system developed by LIVIC. The filter has a number of slotted filter elements inside. When the filter elements are clogged after working for a period,the back-flushing rotation arm cleans the elements one by one and regenerates the filtration capability. XF filter can automatically and continuously work online with no flow interruption. Different from the common weave screen type self-cleaning filters, XF series automatic back-flushing filter adopts the rigid V-SLOT slotted stainless steel filter element with a V-shape opening which is easy to be cleaned. It has the unique advantage when filtering dirty water containing oily sludge, soft and viscous particles, high content impurities and few fibers. The filtration degree ranges from 50 to 2000 µm. Large filter area and high flowrate per unit. 2”~40” inlet and outlet nozzle size available. The flowrate of the largest XF filter model XF1700 is up to 10560m³/h.
