How Blower Fans are Made
factories | fans | machines | metal
Blower fans use a spinning metal cage to move large amounts of air. See how a factory makes these fans in this video from All Process of World. At the core of the operation is a machine that accepts a pair of rings and curved metal blades, then bends the ends to hold them in place. The outer housing is assembled by hand using a rivet gun and power screwdriver.
