Airfoil plug fans are designed with blades that are shaped like an airfoil, providing high efficiency and low noise operation. Direct and belt-driven configurations refer to how the motor powers the fan – directly or via a belt. These fans are particularly useful in applications that require precise control over airflow and pressure, such as in air handling units and large ventilation systems. The airfoil blades reduce turbulence and drag, resulting in lower energy consumption and quieter operation. Their versatility makes them suitable for both residential and industrial applications.
