Centrifugal Fan Driving Modes Advantages and Disadvantages By Xianrun Blower

A Mode: Direct Driving
The impeller of centrifugal fan connects to the motor shaft directly, this is suitable for small airflow and pressure centrifugal blower. 
Advantage: saving the parts (such as belt pulley, belt, coupling, etc.), reliable performance.
Disadvantage: fixed speed. 

High Quality ID Fan for Ventilation

C Mode: Belt Driving
The impeller connects to motor shaft by belt pulley.
Advantage: adjustable speed, motor installation position is flexible. 
Disadvantage: Some parts are easy to break down, and need updating maintenance. 

High Temperature Fan For Metallurgical Factory

D Mode: Coupling Driving
The impeller connects to motor shaft by coupling, coupling drive centrifugal fan for high temperature, large airflow and high pressure condition. 
Advantage: stable operation, high efficiency. 
Disadvantage: fixed speed, high cost.

Wear Resistant ID Fan

How to select the suitable centrifugal fan? The 3rd Stage of Selection by Xianrun Blower

The 3rd Stage of Selection of Centrifugal Fan Selection by Xianrun Blower

According to the known air density, speed, model, and the rough estimate of the fan number, using the drawing function of software, express dimensioned performance curve of the fan, demarcate the fan operating point at the same time, and list dimensioned performance table, demarcate operating point location.

Further more, according to actual working condition performance,finally, determine the fan internal power.

Through the above three stages, and centrifugal fan selection is basically ended. In general, through these blower selection steps, you can choose the most appropriate centrifugal fan.
