I read with interest an earlier discussion on fans. people have preferences for differing reasons. however no one spoke on efficiency.
the two blade.
the four blade
and the plastic six blade.


I am running the plastic six blade. It has a large hub and blade length is short. I wonder if it is efficient. how it compares. Not appearance but ability to move air.


I am open to suggestions. cheers, gary
