Abstract

The present invention relates to an air treatment apparatus (1) having a house (2) housing a suction fan (9). The house (2) has walls (3-8). Air flows through the front wall (5), passes a lateral wall (7 and 8 respectively) and enters into the fan inlet (11) and leaves the house through an outlet (12) in the rear wall (6). With a view to prevent rotation of the air, which flows into the apparatus, guide means (16) are mounted in the space (13) in front of the fan inlet (11), which guide means (16) are made in the form of a triangular plate, the small sides (17, 18) of which extend to the rear wall (6) and one of the lateral walls (7) respectively and the hypotenuse of which (20) lies outside the greater portion of said space (13).
