The impeller has an impeller diameter. A duct is configured to receive an outflow provided by the impeller. The duct has a duct exit diameter that is larger than the impeller diameter. The fan assembly further includes a diffuser collar extending from the impeller toward a duct exit. The diffuser collar is configured and arranged to radially expand the outflow provided by the impeller. The diffuser collar has a first diameter at a first edge disposed a first distance from the impeller. A contour extends from the first edge toward a second edge having a second diameter. The second edge is disposed a second distance from the impeller. The first distance is smaller than the second distance, the first diameter is smaller than the second diameter, and the first and second diameters are smaller than the duct exit diameter.
