MAIN TECHNICAL FEATURES:
HOW IT WORKS
The water enters the filter at (IN) inlet point and runs through the filtering cylinder (1) in outward direction. Thus, all suspended non-deformable solid particles larger or equal to the filtration degree set are retained. The filtered water flows out through the outlet (OUT) pipe.
Constant deposit of suspended solid particles inside the filtering cylinder (1) obstructs the passage of water, causing a pressure differential (∆P). At a preset ∆P value (ranging from 0.3 ÷ 1 Bar) an automatic cleaning cycle of the filtering (1) cylinder starts. This activity begins with a signal that opens the discharge valve (2) allowing communication of the suction nozzles (3) with the outside environment. At the same time, the electric motor’s (4) rotary motion allows the nozzles to inspect the entire filtering surface. Dirt is removed through the discharge valve (2). The cleaning cycle lasts 15 sec.
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 centre. The washing phase can also be controlled manually. The solenoid controlling the valve is pneumatic.
