Claim:
A fan unit having an axial fan ( 20 ; 120 ), associated with which fan is an air-guiding tube ( 22 ; 122 ) through which the fan ( 20 ; 120 ) transports air during operation, said air-guiding tube ( 22 ; 122 ) being joined to at least one suspension member ( 23 ; 123 ) made of an elastomeric material, said suspension member ( 23 ; 123 ) being elastically suspended within a first ring ( 40 ; 140 ) made from a hard plastic, which first ring ( 40 ; 140 ) comprises at least one tubular extension ( 50 , 150 ) made from a soft plastic, for a noise-damping mechanical connection of the fan unit to a carrier part ( 15 ), the tubular extension ( 50 ; 150 ) being connected to a second ring ( 60 ) made of a hard plastic, thereby connecting the tubular extension ( 50 ; 150 ) to the carrier part ( 15 ).
