The walls (18, 20, 22) define at least a first containing compartment (24), able to contain a first filtering element and in which the air to be filtered is able to be introduced through an inlet pipe (32), and a second containing compartment (26), able to contain a second filtering element and connected to the first containing compartment (24) by means of an intermediate pipe (38), and from which the filtered air is able to exit through a discharge pipe (44). The two containing compartments (24, 26) are disposed one inside the other, so that the innermost containing compartment (24) is at least partly surrounded by the filtering element contained in the outermost containing compartment (26).</p> |
