  • Fan wheels of this type are designed in several parts, which inevitably leads to higher manufacturing and assembly costs and thus to higher costs All known fan wheels have these and other shortcomings and require further development in terms of noise reduction to noiseless, increasing the efficiency, reducing the cost and increasing the life.
  • the present invention is intended to make a significant contribution to this.
  • the object of the invention is to disclose a fan, which works with a higher efficiency and lower noise and reduced manufacturing costs while increasing the life.
  • the fan wheel (1) conveys the flow medium inside via the guide blades (5) to the outside, where it emerges essentially radially at the blade wheel outer diameter. Due to the resulting negative pressure in the
  • Impeller inside the fluid is sucked from the outside through the inlet opening (4).
  • the flow direction extends coaxially through the inlet opening (4) into the interior of the impeller and is thereby guided radially outwards. The flow thus enters the annular rotating diffuser (6).
