Stickers have nothing to do with direction of rotation. For actual operation, neither does blade pitch. Most fans are designed to blow one direction, the direction toward which the blades are concave. Wiring determines the direction of rotation. Direction of rotation can be reversed by switching the wires.🙂 Most fans, centrifugal pumps, and clocks😉 are designed/wired to turn clockwise as is this delta fan.
BTW, that fans blows...😛😉
