A centrifugal blower mainly consists of an impeller, volute casing, motor, shaft, bearings, air inlet, and air outlet. The impeller is the core component that generates airflow, while the volute casing collects and converts airflow energy into pressure. During operation, the high-speed rotating impeller draws air through the inlet and increases air velocity by centrifugal force. The kinetic energy is converted into pressure energy, and the pressurized air is collected by the volute casing and discharged through the outlet, providing continuous and stable airflow for various industrial applications.
