Abstract
A roof for the cab of vehicle is constructed with a hollow plastic body that is molded in one piece with a blower and a heat exchanger fitted to the hollow body. The hollow body defines a cavity that forms an air duct through which air for ventilating the cab is ducted. Shuttered external and internal air intake vents allow the selection between fresh air from externally of the cab and recirculated air from within the cab. A well open through the roof provides an emergency exit from the vehicle cab.
