Chemical plants may generate volatile organic compounds, corrosive gases, dust, vapors, and process heat during production. If these pollutants are not removed efficiently, they can accumulate inside the facility, reducing indoor air quality and potentially increasing personnel exposure, equipment c

In mines, tunnels, underground construction sites, industrial plants, and other demanding workplaces, continuous equipment operation and insufficient air circulation can cause heat to accumulate rapidly. High temperatures can affect worker comfort and productivity while increasing the risk of heat s

Blasting is a common excavation method used in mining, tunnel construction, and underground engineering projects. After blasting, the working area may contain significant amounts of smoke, dust, and other airborne pollutants. If these contaminants cannot be removed efficiently, they may affect subse

TBM (Tunnel Boring Machine) construction is characterized by long excavation distances, enclosed working spaces, concentrated equipment, and continuously extending construction routes. As the tunnel advances, conventional ventilation systems may face challenges such as increasing air supply distance

As highway tunnels, railway tunnels, mining tunnels, and TBM construction projects become longer and deeper, long-distance tunnel ventilation has become an important part of construction site management. Due to their narrow and enclosed structures, tunnels have limited natural air circulation. Const

With the continuous development of industrial production, warehousing, logistics, commercial buildings, and urban infrastructure, air pollution control has become an important part of environmental management and ventilation engineering. Dust, odors, volatile organic compounds (VOCs), oil mist, and
