ErP Directive

The ErP Directive 2009/125/EC sets forth minimum requirements for energy-relevant products in order to adhere to the EU's predefined climate goals. The implementation of these requirements takes place for motors according to regulation (EU) No. 640/2009, and for fans according to (EU) No. 327/2011. Compliance with these efficiency requirements is a prerequisite for these products to acquire the CE-certification. External rotor motors are not affected by the motor regulation.

Most ZIEHL-ABEGG fans exceed the ErP requirements both in AC as well as in EC technology and are well equipped for future requirements.
