An AC fan is designed to run on a 50Hz sine wave, and the distorted wave supplied to the fan results in it making a buzzing noise; this will reduce the life of your fan and is highly inefficient.
This Control Freak Frequency Controller is unique in that it precisely alters the frequency of the waves to control the fan speed, which results in super smooth fan control.
