90kW counter-rotating axial flow main ventilation fans have been installed for a coal mine customer. The fan will continuously deliver fresh air underground and improve air quality.

The fan runs at 980r/min with an air volume of 27–65m³/s. It features high efficiency, low noise, compact structure, and reliable performance. Installation is convenient, making it suitable for demanding mining environments.

Advanced technology ensures stable operation. The curved and swept combination orthogonal three-dimensional twisted blade design improves airflow and boosts efficiency. This makes the fan both powerful and energy-saving.

The project enhances mine safety and productivity. With strong performance and advanced blade design, the 90kW counter-rotating axial flow main ventilation fan will support long-term underground ventilation.
