Structure and principle
brush filter is an electrically driven automatically self-cleaning filter. The function of the filter is controlled by a flushing controller. The cleaning process can be activated both automatically and manually. The self-cleaning system makes it possible for the filter cake that has formed on the filter screen to be brushed off, and a great deal of dirt can be removed without interrupting filtration. The short cleaning time of 16-20 seconds, using a minimum of flushing water, is sufficient to clean the entire filter element, with the filtering process being maintained. Features of this unique design are: the electric motor runs the brush axle and the self-regulating brushes over the surface of the screen. The entire screen area is cleaned. Efficient cleaning is achieved by the right contact between the self-adjusting brushes and the screen surface; each brush is pressed carefully against the surface of the screen by two springs.

When the water flow gets through the filter, the impurity in the water is held by the strainer With the increase of the impurity accumulated on the surface of the strainer, the pressure difference reaches 0.04Mpa. The switch of the pressure difference will give out a signal while the PLC sends an instruction to start the drive motor and open the drainage valve; The impurity accumulated on the strainer will be brushed off with the rotating brush and discharged from the drainage exit. The whole process of brushing and draining require no personal operation and without machine halt. At the same time, the equipment is with the function of regular washing and draining and manual washing and draining to make sure that the water output is safe and reliable in any case.




A wide range of Automatically Self-Cleaning Brush Filters are available for very broad application.
The filters are available from 4" to 14" (DN 100 mm - 350 mm) with a capacity of up to 1,000 m/h.
The filter surface varies: 3,250 - 10,400 cm2 and a filter perforation from 200 to 3,000 microns.
The working pressure is 1 to 8 bar (max. 10 bar).
