Large diameter axial Super Low Noise flow fans (2) and commercial air cooled apparatuses incorporating such fans are provided. The large diameter axial flow fan is mounted on the air cooled apparatus (4, 5, 6, 7) for generating an axial air flow in the air cooled apparatus for accomplishing the cooling. The fan has a diameter (11) of at least four feet. The fan has plurality of blades (10). Each blade includes a leading edge (13) opposite a trailing edge (15). The entire of the leading edge (13) of each of the blades (10) is linear and forward swept, and each blade includes a metallic outer surface.
