Suction adapter for filtration screens

A suction adapter for filtration systems having a suction scanner for self-cleaning an area of a screen by suctioning and having space-extensions extending outwardly from a location of the suction scanner and delineated by screen regions contoured between screen troughs and screen crests, wherein at the screen crests an inner face of the screen is remoter from the closest approach of the intake opening of a nozzle of the suction scanner than in the screen troughs, thus a screen area between a screen trough and a respective screen crest is unapproachable by intake openings of nozzles of the suction scanner, the suction adapter comprises:

• a partitioning adapted to match within a space-extension of a predetermined size and shape contoured between a respective screen trough and a respective screen crest, whereby being utilized for tunneling a suction power from an intake opening of the suction scanner to a screen region unapproachable by the intake opening, wherein the partitioning comprises at least one unit of interconnected partitioning segments;
• and
• a perforated sheet having perforations in alignment with cavities formed by the partitioning, wherein partitioning segments protrude toward the screen from a surface of the perforated sheet opposite a surface thereof are to be scanned by the intake opening of the suction scanner.
