• Impellers

  The impellers with 8 backward-curved blades are made of aluminium sheet (AIMg3) and statically and dynamically balanced together with the impeller hub or the external rotor motor used according to the quality level G 2,5 / G 6,3 as per DIN ISO 21940-11. If desired, the wheels can also be manufactured from sheet steel with a plastic coating. The direction of rotation of the impellers is standard clockwise rotation (seen from the suction side). Counter-clockwise operation will cause overload damage to the motor. Therefore, the direction of rotation should always be checked before starting up.
