Centrifugal fans are designed to push air with more force than basic fan types. This allows them to maintain strong airflow even when air has to travel through long duct runs, tight bends, or filters. The result is more consistent and reliable ventilation, especially in systems where airflow resistance would slow down a standard fan.
