They are also aesthetically pleasing with a dynamic blade balance. 3 blade fans also have high speeds and, with fewer parts, they require less energy to rotate. Because the fan is lighter, it doesn’t need as much energy, so you pay less in in energy bills.

How do fans move the air?

Two things on the fan will move the air: If you have a good motor then you can generate a lot of power. You can then adjust the speed to create a stronger air flow. The actual design of the blade, or the angle the blade is set at, also helps move air quicker. This angle is often referred to as the “pitch” of the blade.
