Industry Carbon Steel Auto Self Cleaning Brush Filter for Water Treatment Equipment Self cleaning Filter

In order to achieve the filtering effect, and at the same time to maximize the user to meet the requirements of water, power and labor saving, when you choose the self-cleaning filter, please consider the following technical parameters.

a.Flow rate

b.Inlet & Outlet size

c.Maximum working pressure and temperature

d.Filter strainer type and filtration rating e.Shell material and strainer material

f.Filter suspended substance concentration in impurities

g.Related physical and chemical properties of filter media

h.Based on the local installation position to confirm the structure.

The inside structure of the automatic self-cleaning brush filter is made up of the stainless steel strainer and stainless steel wire brush and transmission part. The washing and the drainage are automatically finished by the drive motor and electrical valve. The operation way is automatic running (manual running is also Ok), It is with the double function of the pressure difference and regularly automatic drainage. The automation part takes use of the most advanced and reliable PLC in the world.

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 0.05Mpa. 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.

• Commercial - Golf course and sporting field irrigation systems.


• Industrial  - Pre-preteatment of UF/RO and waste water recycling.


• Irrigation - Primary filtration for the prevention of blockages in irrigation system


• HVAC- cooling tower side filtration and full system


• Metal Processing Plants - Filtration for water cooling and spray nozzles.


• Mining - Cleaning of process and waste water

How does the self-cleaning filter work?

The water flows through the screen and the particles are retained on the inside of the screen of the filter element. The filtered water then flows out through the outlet.

 When the particles accumulated to a certain number and the pressure differential increases to the pre-determined level, the flushing cycle starts. 

It include two steps: First, the automatic drain valve opens on the drainage outlet. Then, electronic motor drives the cleaning brushes which are inside the screen, the solids are expelled through the drain valve.

Filters continue to supply filtered water even during the flushing cycle.The whole working system is controlled by a smart box which has several control modes: pressure differential, time, manual and PLC.
