<p>The filtering element (1) has bellows (2) whose folds comprise walls (3) and posterior zones (4). A frontal side (5) is turned towards a wall (8) of a casing (7). A hollow guiding column (6) associated to the frontal side traverses or interrupts the walls of the folds. The hollow guiding column is oriented at right angle relative to the walls and the posterior zones of the folds, and is shrunken in a direction opposite to its insertion direction. A signal generating unit e.g. radio frequency identification (RFID) chip, delivers a signal authorizing the identification of the filtering element. An independent claim is also included for an air conditioning system comprising a casing.</p> |
