Abstract
A tractor cab HVAC system has a blower (22) which draws air into the system via air intake means (13) in the roof (14) of the cab (10). Ducting (15) in the roof of the cab directs air drawn in via the intake means down the center of one or more hollow adjacent pillars (16) of the cab to an air filter (18) contained in a housing (20) located between the adjacent pillars. Further ducting (19) extends from the air filter housing to an HVAC unit (11), the HVAC unit processing the air drawn into the system prior to discharging the processed air into the cab. The filter housing (20) is of generally rectangular form and is connected at opposite ends to the two hollow adjacent pillars (16) of the cab via inlet openings (20a) in the housing to allow the passage of intake air from the pillars to the filter (18).
