Definitions

  • the present invention will provide a common and non-divided opening for the air intake and air discharge portions of the fan.
  • the present invention provides that the width of the narrow passageway can be changed, for'example, through a shifting of the fan wheel in order to influence the characteristics of the fan, depending on the duties it is to perfonn.
  • the casing which is open on one side, displaying'an inlet opening 43 and an outlet opening 44, can be covered, for ex ample, by a screen, in order to protect the fan wheel 22 from damage.
  • the flow conditions on the inside and outside of the fan are not influenced by the presence of such a screen.
