Product Application

The mixed-flow duct fan adopts an integrated cylindrical design, allowing seamless embedding and installation in various ventilation duct systems. As a highly efficient and versatile ventilation device, it innovatively combines the high-airflow characteristics of axial fans with the high-pressure advantages of centrifugal fans, making it an ideal solution for ventilation systems in both industrial and commercial settings.

The fan housing is made of corrosion-resistant ABS engineering plastic, offering excellent structural strength and environmental adaptability. Through unique airflow passage design and impeller structure optimization, it achieves a perfect balance between ventilation efficiency and static pressure performance while maintaining a compact size, significantly saving installation space.

Typical application scenarios include:

Environmental control in plant factories and greenhouses
Fresh air supply and exhaust systems in commercial buildings
Kitchen exhaust and air circulation systems
Ventilation and air exchange in underground parking garages and industrial plants

With features such as low-noise operation and high energy efficiency, this product provides a reliable solution for various ventilation needs.
