Dear clients, your feedbacks and wishes helped us to develop and engineer a first line of high-efficient plastic impellers with backward curved blades based on many years of our expertise. 

Numerous trials and test for selection of material and calculation of the most efficient profile of the new impellers with account for the intended operation conditions allowed to enhance the aerodynamic characteristics. The obtained successful results let us implement the new technologies for the existing line of AC fans and a new line for energy-saving EC fans. Blauberg Motoren aims not only to keep pace with the highest ventilation standards, but to set own standards.

Main characteristics:

  • Diameters of the updated impellers: 190, 220 and 250 mm
  • Material: PA plastic + 20 % glass fiber
  • Rotation direction: clockwise
