Contaminant Removal (Air Quality Control): The primary role is to extract hazardous or undesirable airborne materials, such as:
Fumes and smoke (from welding, chemical processes, or commercial kitchens).
Dust and particulates (from manufacturing or processing).
Noxious gases and odors (from chemical storage or livestock facilities).
Thermal Management (Heat Removal): They expel hot, stale air that accumulates due to machinery operation, sun exposure, or industrial processes, helping to regulate and lower the ambient temperature.
