         3 . The fan device as claimed in  claim 1 , characterized in that a part of an air flow of the blower device ( 12 ) is conducted past the regulator device ( 20 ) to the motor ( 16 ) via an air duct guide ( 40 ,  42 ). 
     
     
         4 . The fan device as claimed in  claim 3 , characterized in that the air duct guide ( 40 ,  42 ) has a partition element ( 34 ) which separates the regulator device ( 20 ) from the blower device ( 12 ) in an axial direction while the partition element ( 34 ) leaves the air duct guide ( 40 ,  42 ) open in a radial direction toward the regulator device ( 20 ). 
     
     
         5 . The fan device as claimed in  claim 3 , characterized in that the air duct guide ( 40 ,  42 ) has a partition element ( 34 ) which partially separates the regulator device ( 20 ) from the blower device ( 12 ) and which forms a first air duct section ( 40 ) in which the blower device ( 12 ) is provided and a second air duct section ( 42 ) in which the regulator device ( 20 ) is provided, the two air duct sections ( 40 ,  42 ) being connected to one another. 
     
     
         6 . The fan device as claimed in  claim 1 , characterized in that the regulator device ( 20 ) has a cooling body device ( 24 ), the regulator device ( 20 ) being held in a receptacle ( 32 ) of a housing section ( 30 ) of the fan device ( 10 ) such that the cooling body device ( 24 ) can be impinged on, and cooled, by the air flow of the blower device ( 12 ). 
     
     
         7 . The fan device as claimed in  claim 3 , characterized in that the air duct guide ( 40 ,  42 ) has a first air duct section ( 40 ) for conducting a part of the air flow of the blower device ( 12 ) to a further system. 
     
     
         8 . The fan device as claimed in  claim 3 , characterized in that a first air duct section ( 40 ) of the air duct guide ( 40 ,  42 ) is connected to a fan housing device ( 14 ) which conducts air from the blower device ( 12 ) to a system. 
     
     
         9 . The fan device as claimed in  claim 5 , characterized in that the partition element ( 34 ) has a base ( 44 ) which substantially separates the regulator device ( 20 ) from the blower device ( 12 ) in an axial direction, and the first and second air duct sections ( 40 ,  42 ), the partition element ( 34 ) additionally having a side wall element ( 46 ) which at least partially separates the second air duct section ( 42 ) from a fan housing device ( 14 ) which supplies air from the blower device ( 12 ) to a system that can be connected to the housing device ( 10 ). 
     
     
         10 . The fan device as claimed in  claim 1 , characterized in that the fan device ( 10 ) has one of a clockwise and a counter-clockwise motor. 
     
     
         11 . The fan device as claimed in  claim 3 , characterized in that the part of the air flow of the blower device ( 12 ) is flowing out substantially tangentially from the blower device. 
     
     
         12 . The fan device as claimed in  claim 6 , characterized in that the cooling body device ( 24 ) includes at least one studded area ( 38 ). 
     
     
         13 . The fan device as claimed in  claim 7 , characterized in that the further system is at least one of an air-conditioning system and a fan system. 
     
     
         14 . The fan device as claimed in  claim 8 , characterized in that the system is at least one of an air-conditioning and a fan system. 
     
     
         15 . The fan device as claimed in  claim 8 , characterized in that the fan housing device ( 14 ) is at least one of part of the fan device ( 10 ) and part of the system.
