55kW long distance axial flow ventilation fans improve tunnel air quality

Our 55kW long distance axial flow ventilation fans are engineered to enhance tunnel air quality during construction and mining.

Each fan unit features two 55kW motors, delivering a powerful airflow range from 980 to 630 m³/min. These fans provide static pressure between 1850 and 6800 Pa, making them suitable for long and narrow tunnels that demand consistent ventilation.

One major advantage is the low noise output, operating at ≤25 dB, which helps maintain a more comfortable and safer working environment underground.

The design ensures long-distance ventilation efficiency while keeping power consumption balanced. Their robust structure and stable performance reduce maintenance frequency and operating costs.

Whether applied in mining or civil tunnel projects, these 55kW long distance axial flow ventilation fans are a reliable solution for continuous air circulation and worker safety.
