A fume scrubber is a specialized air pollution control device designed to remove hazardous fumes, gases, and particulates from industrial exhaust streams. It operates by channeling contaminated air through a scrubbing liquid or slurry, which absorbs, neutralizes, or captures the pollutants—effectively purifying the air before it is discharged into the atmosphere.

Fume scrubbers are essential in industries where operational processes emit airborne contaminants, including:

• Chemical manufacturing – to capture toxic emissions such as acids, solvents, and ammonia
• Metalworking – to eliminate metal fumes and particulate dust
• Power generation – to treat harmful gases like sulfur dioxide (SO₂) and nitrogen oxides (NOₓ)
• Radioactive facilities – to control radioactive particulates and vapors

Depending on the application, fume scrubbers can be tailored to target specific gases (e.g., chlorine, hydrogen sulphide) or particulate matter (e.g., aerosols, dust).

These systems play a critical role in ensuring workplace safety, environmental protection, and regulatory compliance related to air quality and occupational health standards.
