From what I could tell it does have blades, they are just inside (notice the air intakes on the base). That air is then projected out the airfoil which draws more air along with it, which allows a much smaller fan blade (housed internally) to move a lot more air. It will also degrade over time (electric motor, and its probably under a heavier load due to having to force air through the airfoil, plus dust etc.)
