Flameproof 45kw extraction type axial flow main ventilator
Flameproof 45kw extraction type axial flow main ventilator boasts a robust structure, exceptionally low noise operation, and impressive high wind pressure. It delivers superior efficiency and stable operation even in confined airflow areas, while maintaining a wide range of highly efficient operation. It can be operated as a whole unit or in single stages, providing the flexibility to optimize energy consumption and achieve significant energy savings. This makes it the ideal equipment for long-distance ventilation in mine roadways, ensuring efficient air circulation throughout the excavation process.

The flameproof 45kw extraction type axial flow main ventilator features a unique counter-rotating impeller stage design. This reduces the number of guide vanes needed compared to traditional two-stage fans, resulting in a more compact size and lower energy losses.
The motor is housed within a flow isolation cavity and cooled by four dedicated ventilation ducts, ensuring optimal performance.
The flow channel is meticulously designed for both efficiency and aesthetics. The curved collector line and hemispherical fairing create a uniform flow field before the impeller, minimizing flow loss. The diameter of the inner cylinder seamlessly matches the impeller hub, maintaining a smooth flow path without abrupt changes. Finally, the tapered diffuser core reduces aerodynamic noise while recovering dynamic pressure.
High-strength cast aluminum alloy ZL104 is used for the fan blades. This material boasts three times the specific strength of regular steel, ensuring the blades won’t crack or break under normal operation. Additionally, the blades utilize a three-dimensional twisted design that combines orthogonal bending and sweeping, achieving a 5-10% efficiency improvement and a 10-20dB(A) noise reduction.
