The possible filtering precision range is 50 to 5000 microns. The filter has a broad filtration area and a high capacity for pollution absorption. Users can tailor the filter to their specific working situations. The cleaning process is straightforward, and cleaning cycle monitoring enables automatic cleaning and sewage disposal. The automatic filter control system's parameters can all be changed. The filter has a motor overload protection function that efficiently protects the motor.
The operating principle
The automatic self-cleaning filter filters the raw water and cleans the filter element automatically, and the system provides continuous water supply during the self-cleaning and sewage drainage processes.

  • Control modes are classified into two types: automatic control and human control.
  • Timing and differential pressure are two methods of automatic control.
  • Setting the filtration timer: Set the filtration timer. When the filtration timer expires, the sewage discharge begins, and the sewage discharge timer determines the sewage discharge time.
  • Differential pressure control: In real time, the control system compares the system's pressure difference to the pressure difference established by the user. 
  • When the system's pressure differential reaches the predetermined value, the filter will automatically clean the filter element and discharge sewage, and the sewage discharge timer will set the sewage discharge time. When the sewage discharge timer expires, the filter will stop self-cleaning and return the system to its initial state in preparation for the next filtration procedure.
  • To discharge sewage, turn the manual/automatic selector switch on the operation panel to the manual position.

  5. Paper
  6. Plastic
  7. Power sectors, among others.


Characteristics of Brush Type Self-cleaning Filter
The filter is designed with mechatronics. The driving mechanism, control pipeline (including the differential pressure switch), main component, filter component, cleaning mechanism, connecting flange, and other essential components make up an automatic self-cleaning filter. The filter's control section is made up of an electronic controller, a control line, and a blowdown valve, which is used to automate the cleaning and blowdown process. The control pipeline is made up of a differential pressure switch, a pipe joint, brass pipe, and various other components. The standard filter comes with a stainless steel brush, but you may also select alternative types of brushes based on your usage conditions (water temperature, water quality).
1) The filter precision is set to 100 microns by default and can be adjusted between 50 and 5000 microns. The filtering area is substantial, and pollution absorption is strong. Users can tailor the filter to their specific working situations.
2) The cleaning process is straightforward, and cleaning cycle monitoring enables automatic cleaning and sewage. The automatic filter control system's parameters can all be changed.
3) The filter has a motor overload protection function that efficiently protects the motor.
4) It contains features such as continuous water supply and no bypass during cleaning and sewage outflow. Furthermore, cleaning time is quick, and sewage discharge consumes less than 3% of total flow.
5) High maintainability, with simple installation and disassembly. The connection flange is quite adaptable.
