Data definition with optimum efficiency. The indicated efficiency values for obtaining
conformity with the Ecodesign Directive EU 327/2011 were achieved with defined air
conduction components (e.g. inlet nozzles). The dimensions are to be requested from ebm-
papst. If other air guide geometries are used on the installation side, the ebm-papst
evaluation loses its validity/conformity must be confirmed again. The product does not fall
within the scope of Regulation (EU) 2019/1781 due to the exception specified in Article 2(2a)
(motors completely integrated into a product).
