ErP “Energy related Products”
All (1) the fans circulating within the European community of power between 125 W and 500 kW from January 2013 will be in accordance with Regulation (EU) N.327/2011 Commission. The efficiency of the fans to meet the European standards, must reach a minimum level. The legislation requires that at least the point of maximum efficiency is greater than or equal to the limits, these limits are fixed with two dates in January 2013 and January 2015. The Regulation states that the verification of compliance with the same regulations can be achieved either through measures that calculations depending on the configuration of the fan.

CMC Srl proof ventilation fans in our laboratory according to ISO 5801 and AMCA 210-07 legislation, the outcome of the tests is achieved compliance with ErP can measure the air flow, the pressure and the electrical power input in the motor. In the assessment of compliance must be taken into consideration all the parts are functionally connected to the fan.
