反冲洗过滤器是一种利用滤网直接拦截水中的杂质，去除水体悬浮物、颗粒物，降低浊度，净化水质，减少系统污垢、菌藻、锈蚀等产生，以净化水质及保护系统其他设备正常工作的精密设备。水由进水口进入自清洗过滤器机体，由于智能化（PLC、PAC）设计，系统可自动识别杂质沉积程度，给排污阀信号自动排污。
XFH Series Automatic Back-flushing Filter is a new generation self-cleaning filtration system independently designed by HANK,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 XFH 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, XFH 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.
XFH Series Automatic Back-flushing Filter, which filtration rating ranges from 50-2000 micron and its line size is available from 2’’ to 24’’.XFH 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.
XFH Series Automatic Back-flushing Filter can remove the solid particles from various water resouce 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. XFH Filter automatically works continuously on-line and reduces the downtime cost, maintenance cost and labor cost. XFH Series Automatic Back-flushing Filter is the advanced solution for the self-cleaning filtrationof water and low viscous liquids.
