<p>The system (10) has an elongated rigid case (2) for defining longitudinal internal volumes within which the pressurized air circulates among an air supply inlet (E) and outlets e.g. holes or slots. The outlets include side outlets e.g. side openings, located on sides of an axis of cross section of the case, and central outlets located between the side outlets. The side outlets generate air flow to drive induction air flow outer to the case and to moves along outer surface of an external portion and front and rear portions of the case.</p> |
