General Information

These automatic electric filters combine the advantages of high quality filtration from different water sources (sewage, reservoirs, rivers, lakes, etc.) with self-cleaning features, offering the customer a continuous water supply.

The filters are designed for use in a wide range of industrial, municipal and irrigation applications.

The inner element is made of stainless steel to withstand high dirt load and pressure. Cleaning of the screen is performed once the pressure loss across the filter has reached the preset value (up to 0.5 bar or 7 psi).

The filter is equipped with a coarse screen that protects the finer screen from stones and larger particles. The flushing valve opens and pressure in the flushing chamber and the dirt collector is significantly lowered resulting in a suction process via the suction nozzles to the dirt collector and from there through the flushing valve outside. The electric motor simultanenously rotates the dirt collector and moves it along its axis. The combination of the vertical movement and rotation guarantees that the suction nozzles will cover the entire internal screen surface, efficiently cleaning the screen.

The whole process takes 15-20 seconds, and the water supply is uninterrupted.
