Abstract
A fan assembly for a work machine includes a fan housing which has a fan guard and a fan shroud defined therein. The fan housing includes a rotationally molded, hollow exterior shell structure. The exterior shell structure is filled with a filler material so as to enhance the structural rigidity and stiffness of the fan housing. The fan assembly of the present invention utilizes fewer components relative to fan assemblies which have heretofore been designed thereby decreasing costs and assembly time associated with the work machine.
