The Axial Type Flow Fans for Mine Ventilation and Tunnel Ventilation breaks through traditional design with its innovative counter-rotating impeller stage. This ingenious feature minimizes the need for guide vanes, resulting in a smaller footprint and reduced energy consumption.

For optimal motor performance, it boasts a dedicated cooling system. The motor sits within an isolated cavity and receives cool air through four strategically placed ventilation ducts.

The flow channel prioritizes both functionality and aesthetics. The meticulously designed curved collector line and hemispherical fairing work together to create a uniform flow field before the impeller, minimizing energy loss. Additionally, the inner cylinder seamlessly connects with the impeller hub, ensuring a smooth flow path without disruptions. Finally, the tapered diffuser core not only reduces noise generation but also recovers lost dynamic pressure, further enhancing efficiency.

Durability and performance are built into the fan blades. Crafted from high-strength cast aluminum alloy ZL104, these blades offer three times the strength of standard steel, ensuring they resist cracks and breakage during operation. Furthermore, the blades feature a unique three-dimensional twisted design that merges orthogonal bending and sweeping. This innovative design translates to a 5-10% improvement in efficiency and a significant noise reduction of 10-20dB(A).
