Chemical warehouses are different from ordinary storage facilities. The raw materials, intermediates, and finished products stored in these facilities may be volatile, corrosive, toxic, or flammable. Some chemicals can release vapors during storage, handling, or packaging. If ventilation is inadequa

Manufacturing plants may generate dust, oil mist, volatile organic compounds (VOCs), welding fumes, acidic or alkaline gases, and other industrial pollutants during production. If these pollutants are not collected and exhausted efficiently, they can reduce indoor air quality and potentially affect

Food processing plants are significantly different from ordinary industrial workshops. Processes such as raw material handling, cooking, baking, cooling, and packaging can generate steam, heat, dust, oil fumes, and odors. If airflow is not properly managed, it may affect the working environment and

The manufacturing of electronic components, semiconductors, and precision electronic products requires a controlled indoor environment. Dust particles, temperature and humidity fluctuations, static electricity, and heat generated by production equipment can all affect product quality and production

As urban underground utility tunnels continue to expand, power cables, communications lines, water supply and drainage pipelines, gas pipelines, and other municipal infrastructure are increasingly installed in centralized underground corridors. Compared with traditional pipeline installation methods

Industrial processes such as cutting, grinding, welding, spraying, crushing, and polishing can generate dust, fumes, oil mist, and other airborne pollutants. If these pollutants accumulate inside a workshop, they may affect the working environment, equipment operation, product quality, and employee
