Rotating Man Door

Rotating Man Door
The rotating man door is mainly intended to be an pedestrian door for underground ventilation purposes. The rotating door eliminates the possibility of leaving doors open which adversely affect the balanced flow of ventilation in ventilation districts. These doors are normally installed adjacent to the main ventilation access doors but allow safe and free access for pedestrians without air leakages when using the door. Each compartment or section of the rotating door is sealed off to prevent air leakages and a sight port for forward view whilst using the door.
