After all the fixation is completed, the arc-shaped slider drives the fan blades to slide along the annular groove and connect with the mounting ring sleeve through the drive, thereby forming wind force, and bringing the external airflow into the ventilation duct body through the air inlet pipe. When the wind force is formed, the airflow enters the ventilation duct body through the air inlet pipe, and then passes through the filter plate and the activated carbon placed in the grid placement box to filter particulate matter and harmful gases, and then enters the civil air defense project through the air outlet pipe.

[0014] 2.
