Structural type: Cantilever type, no bearing, the fan impeller is directly mounted on the motor shaft, the speed of the fan is the same as the speed of the motor.
Advantage: Simple and compact structure, small fan volume, high mechanical efficiency of the fan.
Disadvantage: The fan model is smaller and cannot meet the requirements of large air volume or high pressure.
Main applications: Due to the bearing capacity of the motor or the effect of the medium (such as high temperature), it is only suitable for small fans with no special requirements for the medium.
