Jifu Direct-Connected Vacuum Equipment, the Upgraded Choice: The structure with the separation of the main machine and the motor solves the problem that the integrated single-bearing motor is prone to the phenomenon of the rotor rubbing against the stator. The middle bracket structure in the direct connection drive ensures that the main machine and the motor remain concentric, avoiding abnormal wear of the bearings. The dynamic balance treatment of the main machine rotor makes it durable and quiet, and the thickened bottom plate is stable with a low dynamic load. It is equipped with a large-flow internal fan, which has excellent heat dissipation performance. The externally installed enhanced variable-capacity resonance chamber silencer has an outstanding noise reduction effect. It is also equipped with an Internet of Things system, allowing users to check the equipment status through their mobile phones. Moreover, the filter element can be cleaned, saving money for users.
