This disclosure relates generally to fan shrouds for machine fans, and, more particularly, to the structure and design of double bell mouth shrouds and placement of double bell mouth shrouds relative to a machine fan. In some examples, a fan shroud encircling a circular fan having a plurality of fan blades can be provided. Some example fan shrouds can include an inlet adapted to receive air and an outlet adapted to outlet air. The inlet can include an inlet radius, and the outlet can include an outlet radius. In some examples, the outlet radius can each be about 10% of the fan diameter.
