Abstract
Air conditioning apparatus for a tractor cab in which filter and air inlets are disposed in a portion of the roof projecting rearwardly beyond the cab, the air inlet being downwardly disposed so that foreign matter accumulating in the exterior of the filter is free to fall off of the filter and out through the air inlet. The heat exchange means for removing heat from the air is located behind and beneath the cab seat with the air outlet opening into the cab so as to direct cool air into the cab behind and beneath the operator. The cab may have one or more rear corner posts which are hollow and the air passing through the filter is passed through at least one of these hollow corner posts to the heat exchange means. The filter preferably extends transversely with respect to the cab. Two filters may be employed, these filters being spaced apart with a booster fan located between the filters and directing air passing through the filters downwardly to the heat exchange device. Preferably the main air circulating means is located adjacent the heat exchange means. The filter may be of the cylindrical type, the air passing from outside of the cylindrical surface into the cylindrical interi…
