What is the difference between a 3, 4 or 5 blade fans?
There is not a great deal of difference between the performance features of a 3,4 or 5 bladed fan. Generally speaking 3 bladed fans are usually made from metal blades and therefore move a significant amount of air, however the down side is that they will produce a little more noise than a timber bladed fan. 5 blade fans will usually require a larger motor to push the 5 blades around and larger motors generally mean more energy is used. 4 bladed fans are the most common ceiling fans available.
