Overview
Negative pressure ventilation ducting, also known as exhaust ducting, is specifically designed to extract contaminated air, dust, and harmful gases from subway tunnels, thereby improving air quality. By creating a partial vacuum, or negative pressure, this system pulls out polluted air and exhausts it outside the subway tunnel environment. This form of ventilation is essential not only during subway construction and maintenance but also as part of the daily operations to maintain safe air quality levels.
