Principle

DLDZ series electric automatic backwash filter consists of filter body, differential pressure switch, program controller, drain valve and cleaning actuator.

When there is a dirty substance in the filter body, the differential pressure switch sends the detected differential pressure signal to the program controller, and the program controller processes the signal, instructs the cleaning actuator to perform the cleaning work, and simultaneously instructs the drain valve to open for sewage discharge.
