Working Principle

Automatic self-cleaning filter has the function of filtering the raw water and cleaning the filter element automatically, and the system will provide uninterrupted water supply during self-cleaning and sewage draining process.
There are two kinds of control mode: automatic control and manual control.
Automatic control: Automatic control has two ways of timing and differential pressure.
Timing control: Set the filtration time on the filtration timer. When the filtration time is up, the sewage discharge is started, and the sewage discharge time is set by the sewage discharge timer.
Differential pressure control: At the same time, the control system will compare the pressure difference of the system with the pressure difference set by the user in real time. When the pressure difference of the system reaches the setting value, the filter will also clean the the filter element and discharge sewage automatically, and the sewage discharge time is set by the sewage discharge timer. When the sewage discharge time is up, the filter will stop self-cleaning process and restore the system to its initial state to prepare for the next filtration process.
Manual control: Turn the manual/automatic selector switch on the operation panel to the manual position to discharge sewage.
