<p>The unit comprises a body (11) that is shaped like a parallelepiped and is delimited by a front wall (11a) and by at least two side walls (11b-11c). The front wall is provided with cylindrical unions (12a-12b) that end directly with respective front air delivery vents (13a-13b), and the side walls are provided with corresponding cylindrical unions (12b-12c) for connection, by means of corresponding ducts (16c-16d), to respective lateral delivery vents (13c-13d). The front and lateral unions are provided with respective valves (18a-18b-18c-18d) for adjusting and interrupting the flow; these valves are affected by corresponding centralized controls constituted by individual rotatable knobs (20a-20b-20c-20d) that are arranged frontally below the corresponding front vents (13a-13b). <IMAGE></p> |
