In mining, tunnel construction, underground engineering, building construction, and industrial production, dust is one of the major challenges that ventilation systems need to address. High-dust environments can affect air quality in working areas while also increasing equipment maintenance requirem

In underground projects, tunnel construction, mining operations, underground parking areas, and other enclosed or semi-enclosed environments, an effective fresh air supply is essential for maintaining a comfortable and safer working environment. Because enclosed spaces have limited natural airflow,

Confined working spaces are commonly found in tunnel construction, mining operations, underground engineering, pipeline maintenance, equipment inspection, and industrial construction sites. Because these areas have limited space and restricted airflow, heat, dust, smoke, and exhaust gases generated

In tunnel construction, mining projects, underground engineering, building construction, and large industrial projects, temporary work areas are constantly changing. As construction progresses, workers, equipment, and work faces may move frequently, making traditional fixed ventilation systems less

Large underground spaces include underground parking garages, commercial facilities, mines, tunnels, and underground construction sites. Because these environments are enclosed and have limited natural air circulation, dust, smoke, exhaust gases, and heat can easily accumulate. An efficient mechanic

During industrial production, welding machines, cutting equipment, grinding machines, chemical processing equipment, and various types of manufacturing machinery may generate dust, fumes, hot air, steam, and odors. If these pollutants are allowed to spread throughout the workshop, they can reduce in
