A centrifugal fan is a mechanical device used to move air or gases by converting rotational energy into increased air pressure. It works by drawing air into the center of a rotating impeller and then discharging it outward at a right angle, making it suitable for applications requiring high pressure and controlled airflow.

Centrifugal fans are widely used in HVAC systems, industrial ventilation, dust collection, and exhaust applications. They are efficient, reliable, and capable of handling air with particulates, moisture, or high temperatures, depending on the design and materials used.
