A centrifugal fan is a mechanical device for moving air & other gases. These fans increase the speed and volume of an air stream with the rotating impellers. Centrifugal fans displace air radially, changing the direction (typically by 90°) of the airflow. They are sturdy, quiet, reliable, and capable of operating over a wide range of conditions
They are used in transporting gas or materials and in ventilation systems for buildings and vehicles. They are also well-suited for industrial processes and air pollution control systems.
