  • Low-noise operation due to low circumferential speeds and high pressure coefficients.
  • Optimised outlet guide vanes to increase the pressure coefficients.
  • Extensive adjustments to the relevant operating point and subsequent motor rating corrections can be made by steplessly adjusting the impeller blades without any need to disassemble the impeller (the impeller blades cannot be adjusted in the case of the F400 temperature class).
  • The desired operating point is optimised to achieve the best possible efficiency using a variable number of blades (6 / 9 / 12).
