Why should fans be equipped with IE3 motors?

On the market, you can still find fans with low-efficiency motors, because these motors are cheaper (mainly due to the smaller amount of copper contained). High-efficiency motors have up to twice as much energy loss, which directly translates into electricity costs. So it's not worth being tempted to make apparent savings in the form of a lower purchase price, especially at current energy prices.

Since electric motors account for a large share of global energy consumption, the European Union, under Ecodesign, has decided to phase out low-efficiency electric motors, forcing the use of high-efficiency motors.

When buying a fan in which the electric motor is powered directly from the power grid, it should be remembered that it should meet the requirements of efficiency class IE3 (Premium Efficiency).
