Retrofitting fans
There is more and more interest in energy-efficient
fan solutions on the market.

Fan replacement by ebm-papst

Fixed-speed asynchronous motors are still often implemented to drive fans in the refrigeration, air conditioning and building services sector. But these have one major drawback: relatively poor efficiency. This has negatively effects energy consumption in virtually all applications.

There is a way to save energy: ebm‑papst can replace fans that use AC motors and are usually inefficient with highly efficient EC technology in the same mechanical design. Switching from AC to EC fans not only benefits the environment and cuts operating costs, it also enhances comfort.

Advantages of EC fans

EC motors are extremely efficient, unbeatably compact and operate very smoothly. Their efficiency levels are always superior to common asynchronous motors. The energy-saving motor’s efficiency levels already far surpasses efficiency class IE4. And it is considerably quieter than conventional belt-driven AC fans.

The EC motor is equipped with control electronics, permitting precise adjustment of the air volume to suit requirements. It is also offers advantages in terms of EMC issues, and the unit only has to be connected to one supply point. EC motors have established themselves as fan drives in many fields. The term “EC motor” is often used for different concepts, but one thing is always the same: The way that lovebet EC motors from ebm-papst are designed makes critical rare-earth magnets unnecessary.
