Zusammenfassung:	An integrated diffuser grille 34 for a coil unit 20 includes a hub 50, a stack diffuser wall 52, a plurality of radial spokes 54 extending between the hub 50 and the stack diffuser wall 52, and a plurality of partial spokes 56 extending inwardly from the stack diffuser wall 52. A radial length of the partial spokes 56 is less than a radial length of the spokes 56. A plurality of circumferential elements 62 is connected to the plurality of radial spokes 54 between the hub 50 and the stack diffuser wall 52. At least one circumferential element 62 is connected to the plurality of partial spokes 56 and at least one circumferential element 62 has a non-uniform configuration about a circumference of the plurality of circumferential elements 62. A cross-section of the plurality of radial spokes 54 has an airfoil-shape and at least one of a spoke pitch angle, camber angle, and chord of the airfoil-shape varies over a radial length of the plurality of spokes 54.
