Abstract

Axial flow fan assembly, characterized by comprising a fan ring, first and second axial current fans mounted coaxially within the fan ring or surround to cause air to move in the direction from the first to the second fan, having the fins or blades of the second fan an average pitch or advance greater than the average advance of the fins of the first fan, and the elements to rotate the fans at a desired speed, the axial spacing between said fans being considerably less than what would be necessary for the fans to perform the same useful work with their fins having the same advance or medium pitch and to rotate at the desired speed.
