Abstract: Cabin air treatment apparatus for an agricultural machine, comprising at least an external air inlet (11, 16), a filtration system (20), an HVAC system (30), and a cabin air supply outlet (40). The apparatus further comprises a hermetically closed box (1) inside which the HVAC system (30) is housed, the box having a levelling opening (60) for placing the box (1) into communication with a cabin (C) of the agricultural machine to level a pressure inside the box (1) with a pressure inside the cabin (C), wherein said at least one external air inlet comprises a first external air inlet (11) formed on the box (1). The filtration system comprises a first filter (21) for effecting a filtration of at least one among dust, aerosols and vapours, arranged at the first air inlet (11), and a blower (22) for drawing air from the first air inlet (11) and delivering it to the HVAC system (30), said blower being arranged directly connected downstream of the first filter (21) and inside the box (1).

Abstract: A roof of a cab comprising a load-bearing structure made of plastic material, and a heat exchange assembly for treating an airflow, the heat exchange assembly being borne by the structure made of plastic material and comprising at least one heat exchanger and at least one ventilation unit. The load bearing structure comprises a central section in which is housed the heat exchange assembly and in which is defined a chamber for collecting the treated airflow. The load bearing structure further comprises a central section for the distribution of the treated airflow towards the interior of the cab, the annular channel surrounding the central section and communicating with the collection chamber.
