The tunneled tunnel fan is a form developed by using linear bearing system of fans used for exhaust ventilation and fire smoke evacuation in tunnel ventilation systems.This system allows the full maintenance of the fans without disassembling them. By adapting the linear bearing system to the motor support legs to which the motor and propeller are connected, the electric motor and propeller can be shifted in the fan to make the necessary maintenance easier and the motor can be removed more easily when necessary. With the use of linear bearing system, maintenance, time saving, labor saving and job security are provided.
