Namaa Centrifugal Fan
Centrifugal fans are used if applications need higher pressure with the same or higher airflow than axial fans.
A centrifugal blower draws in the air through the inlet axially (in parallel) to the drive axle, deflects the airflow 90 degrees through the rotation of the impellers and extracts it radially.

The airflow is extracted in a specific direction with blowers with a spiral housing.
A centrifugal fan without a housing extracts the air radially out of the impeller with curved blades.
Centrifugal blowers cover the widest performance range.
