                     The Working Principle of Centrifugal 
Fans Explained
What Is a Centrifugal Fan?
A centrifugal fan, also known as a blower, is a mechanical device that moves air or gases using 
the centrifugal force generated by a rotating impeller. Unlike axial fans, which move air along 
the axis, centrifugal fans push air at a 90-degree angle to the intake, allowing for higher 
pressure airflow in confined systems.
How Does It Work?
1. Air Intake
The process begins when air enters the fan through the center, or inlet, of the impeller. This 
central location is known as the eye of the fan.
2. Impeller Action
Once the air is drawn in, it hits the rotating impeller blades. These blades are designed in
 various shapes (forward-curved, backward-curved, or radial) to control the direction and 
force of airflow.
3. Centrifugal Force
As the impeller spins, it creates centrifugal force, flinging the air outward toward the edges 
of the fan housing. This increase in kinetic energy results in higher air pressure.
4. Outlet Discharge
The high-pressure air is then directed out through the fan outlet, usually at a 90-degree angle
 to the intake. This pressurized flow is ideal for ventilation through duct systems or across 
large industrial areas.
