I bought a second hand fan and now have a problem. It is probably off a Vauxhall ,marked GM. It works both ways, but, one way air blasts out the other it doesn't. In the 'Car builder' catalogue it says 'On curved blade fans the pointed end should trail'. On my fan this seems less efective. A house fan leads with the pointed end. Any words of wisdom?

Re: Fan Rotation
From decades gone by the idea of a trailing edge fan was to reduce noise, but blades can be designed in either direction and most fan manufacturers don’t bother to mark that on the fan itself.
i know it’s no help but I have been aware of the issue since I worked at an industrial air movement company since the mid 70’s and we made fans that went both ways. -
