What is the Fan Assembly made of?
All of our Fan Assemblies are constructed of 22 gauge Galvanized steel fan blades and Tail Rudders attached to a painted steel structure and spinning on a pair of maintenance free durable hubs with sealed bearings. The heavy duty Fan Assemblies are built to withstand the elements and can’t be compared to the lightweight garden variety windmills available at the local department stores. The 20’ Fan Assembly has 2 sets of hubs and sealed bearings, one for the actual fan and another set where the horizontal stabilizer attaches to the vertical rod extending up from the derrick tower.
