[Healeys] Kenlowe

[Michael Salter]

So just to be clear ...

You have fan, you take the blade assembly off the shaft, flip the blade
assembly over and reinstall it onto the shaft and then, when the fan blades
are driven in the same direction of rotation direction as previously the
air movement will be reversed?

The miracles of modern science.
