There are many kinds and types of blowers, one of which is a centrifugal fan. This product is designed with a fan or a propeller rotation with a centrifugal motion. This product has a shape resembling a conch with a certain size depending on the specifications inside. The use of centrifugal fans is common in Indonesia. Able to generate wind pressure that is large enough, thereby reducing air humidity.
The way a centrifugal fan blower works is similar to a centrifugal pump, air enters through the inlet side 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. In the industrial world this fan is often given the term blower.
