A centrifugal blower is a mechanical device used to increase or increase the pressure of the air or gas to be flowed in a certain room as well as suction or vacuuming of air in the room, so that air circulation is better.
This centrifugal fan works with the system of air entering through the inlet side which is at the center of the centrifugal fan rotation, then pushed away from the fan shaft due to the centrifugal force from the rotating fan blades. At the same flow rate, centrifugal fans produce a greater outlet air pressure compared to axial fans.
