What is a scrubber fan?

• A. A cooling fan
• B. A fan mounted as part of a machine to control dust around the machine and to assist in ventilating a working place
• C. A fan used to ventilate a mine
• D. A fan used to scrub water

Answer: (B)

A scrubber fan is a fan mounted on or integrated with mining equipment to control dust at the source and help ventilate the immediate work area. It pulls air through a dust-suppression scrubber (often using water to capture dust) so the air around the machine is cleaner and airflow around the operator is maintained. This is distinct from a general cooling fan, which mainly serves to cool equipment or personnel, and from a larger mine-wide ventilation fan, which moves air throughout a whole section of the mine. It’s also not simply about scrubbing water in a separate system; the key role is moving air through a dust-control scrubber to reduce dust exposure right at the machine.
