A filter cart and a maintenance platform are arranged on the steel platform. Fresh air enters the dynamic pressure chamber through the air supply air conditioner and the air supply duct. The dynamic pressure chamber can reduce the swirl and turbulence of the fresh air and reduce the amplitude of local high and low pressures. The air after pressure equalization in the dynamic pressure chamber will enter the static pressure chamber.
