The way a centrifugal blower transports gas is through the rotation of the impeller. The gas is sucked in axially, accelerated along the radial blades, and finally discharged along the tangential direction of the impeller, resulting in airflow. The pressure generated by the blower needs to overcome the resistance generated by the accessories installed at the exhaust port (such as connection joints, pipes, filters, and other accessories). When the gas flow rate increases, the pressure generated will decrease, and the performance of the blower depends on its design and size.
A centrifugal fan draws air axially relative to the drive shaft, rotates the radial impeller to turn the air 90 °, and then blows it out radially. When there is no casing, a radial fan will blow air radially out of the impeller. The centrifugal fan covers the widest power range in the Elektror product portfolio, providing power up to 9500 m/h and 20800 Pa.
