Most of the Elixir motors have a D shaped shaft that the fan blade fits onto which is an outdated style. We do not have any replacement fan blades that fit the D shaped shaft of the motor and from my research they can be hard to get a hold of.
One option is to replace the motor with part # BVD0218-00 and then use a new 6 inch fan blade part # BVC0466.
I recommend to just replace the Elixir Vent with an updated Fan-Tastic Vent part # FV800601 because the parts will be easier to replace... view full answer...
