Data obtained at optimum efficiency level. The efficiency values displayed for achieving
conformity with the Ecodesign Regulation EU 327/2011 has been reached with defined air
duct components (e.g. inlet rings). The dimensions must be requested from ebm-papst. If
other air conduction geometries are used on the installation side, the ebm-papst evaluation
loses its validity/the 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).

For continuous operation at ambient
temperatures below -25°C (such as
refrigeration applications), use must be
made of a fan design with special low-
temperature bearings.
