Abstract:
The invention relates to a fan unit, having an air guide tube and a fan grate, wherein an air channel is formed by the air guide tube and the fan grate is arranged over a first end opening of the air guide tube in order to protect a fan wheel that can be arranged within the air guide tube. In order to improve such a fan unit in such a way that vibrations can be reduced in a simple and effective manner, at least three damping elements are arranged between the air guide tube and the fan grate in order to reduce vibrations.
