Introduction to Tangential Cross Flow Fans

Tangential cross flow fans are unique in their design and airflow characteristics. Unlike axial or centrifugal fans, these fans move air perpendicularly across the fan's axis, producing a wide, uniform airflow pattern. This makes them ideal for applications requiring consistent air distribution over a broad area, such as air curtains, HVAC systems, ovens, and electronic cooling.

How Tangential Cross Flow Fans Work

The fan consists of a cylindrical impeller with multiple forward-curved blades mounted on a hub connected to a motor shaft. As the impeller rotates, air is drawn in from one side, passes through the blades, and is expelled evenly across the entire length of the fan, creating a laminar airflow. The fan housing includes a vortex tongue that directs airflow and creates a pressure difference necessary for efficient operation.

This design allows tangential fans to deliver a smooth, broad airflow that is less turbulent than that of other fan types, making them particularly suitable for applications where even air distribution is critical.
