What type of fan is mostly used in HVAC and industrial systems?

Centrifugal fans are predominantly used in HVAC and industrial systems due to their ability to generate high pressure and move large volumes of air efficiently. They operate by drawing air into the center of the fan and then forcing it outwards through a discharge nozzle. This design allows centrifugal fans to handle high resistance in the ductwork and achieve sufficient airflow, making them ideal for applications requiring consistent and controlled airflow, such as in heating, cooling, and ventilation systems.

Furthermore, their versatility makes them suitable for various configurations and applications, whether in commercial buildings, industrial processes, or even in more complex systems requiring precise air management. The characteristics of centrifugal fans allow them to be effective in situations where other fan types may not perform as effectively, such as in systems that require high static pressure or in circumstances where air needs to be moved through long duct runs.
