Ecodesign requirements for fans

Since 2013, it has been a requirement that all fans between 125W and 500kW must meet a minimum efficiency level (N) at the best operating point.

The different fan types are measured using different methods. This is necessary to take into account the characteristics and applications of the individual fans – as the efficiency has an influence here.

The diagram below shows the minimum requirements for the different fan types. This means that the total efficiency of the individual motor/fan must be above the applicable curve.

Fans with the designation VSD (variable speed drive) can be set to the desired operating point and are typically fans with FC or EC motor – shown here with dotted line. Fans with voltage-regulated motors must meet the requirements shown with a full line.

Which values should be entered for fans

• Real efficiency at optimal operating point
• Measurement method used
• Efficiency (N) is a mathematical conversion to 10 kW so that the efficiency can be checked in Regulation EC327/2011

EXHAUSTO has tested its entire product range in accordance with the requirements and has ensured that all products comply with the 2015 requirements. Among other things, we have introduced EC motor technology, thereby increasing energy efficiency even further. This means that all EXHAUSTO fans have an efficiency level well above the minimum requirements from 2015.
