Product Description

Working principle
When the self-cleaning brush screen filter recognizes too much dirt building up on the surface of the filter screen as well as a pressure difference between the inlet and outlet water reaching a preset value, it will automatically start its self-cleaning program. This entails the motor driving a rotating brush to remove the dirt buildup from the filter screen and switch on the electric valve for discharging the dirt. This effectively cleans the filter back into its optimal filtering state.

characteristic

The time allocated for cleaning can be adjusted to fit your needs, ranging from 20 to 120 seconds.

No need to turn down the water during self-cleaning.

The pressure loss caused by blowdown less than 0.5 bar.

The flow deviation limited to less than 1%.
