Even having worked that out, I kept hitting one issue after another... like physically mounting it, in the right place, and the blades on a normal fan all seem to be either to big, or too small, finding a fan where the blades are actually 9" was not easy. I couldn't use the old fan blades, as the motor shafts on all the fans I checked out, were a lot thinner than the original one. On top of that, the cost of a reasonable fan was more than I managed to get that unit for.

I thought of using a car radiator fan, as they are nice and slim, reversible plus have all the right mountings, but not only are they very noisy, but it then opens a whole new bag of worms, as I would need a high current mains to 12v converter, and find somewhere in there to hide that...

Yeh my fan was quite cheap I think I got a deal on it, however it is a good one and probably cost a fair bit more today, messing about with converters etc gets messy and you end up with franken-con in your van, glad you got that bit sorted and if rick can't sort the gas out I'll eat my underpants
