Structure Of A Centrifugal Fan

A centrifugal fan is primarily composed of components such as the motor, volute casing, impeller, inlet and outlet ports, duct connection ports, oil plug, and inlet air chamber. The motor is powered by an external supply and drives the rotation of the impeller. The impeller is the core component of the fan; factors such as its rotational speed, outer diameter, and blade angle determine the gas flow rate and air pressure, while the material of the impeller significantly impacts the fan's service life and reliability.
