Tangential cross flow fans, also known as cross flow or tubular fans, are essential components in many industrial and commercial applications due to their unique design and airflow characteristics. They produce a wide, uniform airflow across their entire length, making them ideal for cooling, ventilation, and drying tasks where consistent air distribution is critical. In America, several top manufacturers specialize in producing high-quality tangential cross flow fans that meet diverse industrial needs. This article explores these leading manufacturers, their product features, applications, and the technology behind tangential cross flow fans.
Tangential cross flow fans consist of a long cylindrical impeller with multiple forward-curved blades arranged along the impeller's length. When the impeller rotates, air is drawn in from one side of the fan housing and expelled perpendicularly across the entire length of the fan, creating a broad, laminar airflow pattern. This design allows for uniform air distribution over a wide area, which is a significant advantage over traditional axial or centrifugal fans that direct airflow in a more concentrated stream.
The compact and elongated shape of these fans makes them suitable for applications with space constraints. They operate quietly due to their low velocity airflow and have low mechanical vibrations, contributing to their suitability in noise-sensitive environments.
The fan's impeller, enclosed in a vortex housing, rotates to pull air in from one side. The forward-curved blades push the air through the impeller, and the air exits on the opposite side in a smooth, even flow. This crosswise movement of air is why these fans are called cross flow or tangential fans. The design ensures that air moves uniformly across the entire width of the fan, providing consistent cooling or ventilation.
