HOW IT WORKS
Water enters the filter through the IN inlet and goes through the filtering cylinder from the inside to the outside. This will retain all non-deformable suspended solids that are the same size or bigger than the filtration degree installed. Filtered water leaves through the outlet pipe (OUT).

REGENERATION
The continuous settling of suspended solids inside the filtering cylinder obstructs the passage of water which results in a pressure difference (?P). At a preset value of ?P (range 0.3 ÷ 1 Bar) an automatic cycle will start to clean the filter cylinder, this operation begins with a signal that opens the discharge valve (2) and creates communication between the suction nozzles (3) with the outside environment. At the same time, the electric motor (4) creates a rotating motion which enables the nozzles to inspect the filtering surface. Dirt is ejected through the discharge valve (2). The cleaning cycle lasts approximately 15 seconds.

CONTROL
A switchboard controls the washing phases. The signal that starts the cleaning cycle is given by a differential pressure switch. The switchboard gives an “alarm” signal in case of problems in the washing system. These signals can be sent to a pre-existing control center. The washing phase can also be controlled manually. The solenoid controlling the valve is pneumatic.
