Features:
1. Less pressure loss, less backwashing: filtration pressure loss: ≤0.05MPa, backwashing displacement ≤0.5% filtered water
2. High degree of automation: The self-cleaning filter should be backwashed by its own water pressure and filtered water to automatically discharge the dirt, and it is still in the normal water supply filtration state during the backwashing process.
3. Various control methods: cleaning control mode: differential pressure control, timing automatic control and manual control. The control system not only sets differential pressure cleaning, but also has timing cleaning function (adjustable flushing interval) and continuous cleaning function, control system. It can meet long-term continuous work, and can automatically clean the filter and clean it thoroughly.
4. Simple control operation: With differential pressure/manual/time control function, the backwash pressure difference, backwash cycle and backwash time can be set separately on the controller.
5. easy to install, by accounting for a small area

Product structure

Principle description

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

Self-cleaning mode can be started by pressing, timing or manual three ways, following the principle of pressure difference.

When the internal and external pressure difference reaches the set value, the self-cleaning mode starts.Drain pipe hydraulic valve open, sucking the scanner to produce negative pressure suction nozzle inside, absorbing impurities, at the same time sucking scanner in under hydraulic motor along the inside surface mesh do reciprocating screw, movement, no cleaning blind area, impurities by the discharge outlet.

The cleaning time of self-cleaning filter is set by the controller in advance, the drain valve is closed after cleaning, and little water loss in cleaning process.
