A ventilation assembly includes an air intake channel; a delivery channel; a generating device of an air stream between the intake channel and the delivery channel; a filtering section of the air stream to decrease, if not eliminate, the presence of particulate in the air stream. The filtering section includes a filter having a containment body provided with an intake opening and a delivery opening for the air stream passing therethrough, and air-tight bulkheads, arranged inside the containment body and shaped to force the air stream to collide therewith and with the inner walls of the containment body, the bulkheads and the containment body having a section portion suitable for being penetrated by the particulate in the air stream so as to retain it therein.
