I'm after a couple of small centrifugal fans, for blowing air. They are to replace some that I might be able to re-use but would prefer not to.
They fit on a 1/4" shaft and are about 20cm and 12cm diameter respectively. The existing ones are very crude being just a set of flat blades rivetted onto a round plate which has a central collar that fixed onto the motor shaft.
Can anyone suggest a supplier of such things? I might even find some that are rather better made than the existing ones, I can't imagine anything much worse.
