A low tone axial flow fan structure includes a hub an inner fan including a number of inner blades attached to the hub and extending radially outwardly to a first circumferentially extending blade support structure and an outer fan including a number of outer blades attached to the first circumferentially extending blade support structure and extending radially outwardly to a second circumferentially extending blade support structure The number of outer blades defines an outer fan blade passing order. The number of inner blades ensures creation of blade passing orders or multiple of said blade passing orders within one blade passing order of the outer fan blade passing order so as to provide masking of the outer fan blade passing order.
