What is the primary function of a scrubber fan?

• A. To power the machine
• B. To control dust around the machine and assist ventilation
• C. To cool the mine air
• D. To compress air

Answer: (B)

The main function of a scrubber fan is to control dust around the machine and assist ventilation. It works by pulling air through a scrubbing medium (often involving water sprays) to capture and remove fine dust particles as air is moved away from the face. This reduces respiratory dust exposure for workers and helps direct contaminated air into the mine’s ventilation system, improving overall air quality and flow near the equipment. It is not used to power the machine, cool the mine air, or compress air.
