fan blades are inclined to an angle of less than 90 degrees. When a fan motor turns the blades, the blades move through the air at an incline; the inclined surface passing through the air pushes the air forward, as the air is scooped up by the leading edge of the fan blade and set in motion as it passes over the surface.
