Ecodesign requirements for fans driven by electric motors
Introduction
The Commission of the European communities has published a directive for the setting of
ecodesign requirements for energy- using products:
"Directive 2009/125/EC of the European Parliament and of the Council
with regard to ecodesign requirements for fans driven by motors with an
electric input power between 125 W and 500 kW".

This page explains the scope of this document and the impact on the fans and electrical motors.
Subject matter and scope
1.'Fan' means a rotary bladed machine that is used to maintain a continuous flow of gas,
typically air, passing through it and whose work per unit mass does not exceed 25 kJ/kg,
and which:
- is designed for use with or equipped with an electrical motor with an electric
input power between 125 W and 500 kW (≥ 125 W and ≤ 500 kW) to drive the impeller at
its optimum energy efficiency point,
- is an axial fan, centrifugal fan, cross flow fan or mixed flow fan,
- may or may not be equipped with a motor when placed on the market or put into service;
2. The new regulation shall not apply to motors
specifically designed to operate:
- designed specifically to operate in potentially explosive atmospheres
as defined in Directive 94/9/EC of the European Parliament and of the Council;
- designed for emergency use only, at short-time duty,
with regard to fire safety requirements set out in Council Directive 89/106/EC;
- designed specifically to operate:
- where operating temperatures of the gas being moved exceed 100 °C;
- where operating ambient temperature for the motor,
if located outside the gas stream, driving the fan exceeds 65 °C;
- where the annual average temperature of the gas being moved and/or
the operating ambient temperature for the motor, if located outside the gas stream,
are lower than - 40 °C;
3. As from 1 January 2013 ventilation fans shall not have a lower target
energy efficiency than as defined in Annex I, Section 2, Table 1;
