mine auxiliary fan

Mine auxiliary fans—also known as booster or secondary fans—are installed deeper in the mine to overcome pressure losses and deliver fresh air to remote faces, crosscuts, and dead-end drifts.

These fans are usually compact axial or centrifugal units, designed for easy relocation as mining advances. Their impellers are dynamically balanced and housed in corrosion-resistant steel to withstand harsh conditions.

Controlled via VFDs, auxiliary fans adjust speed based on airflow measurements and sensor feedback, providing targeted ventilation where primary fans cannot maintain adequate pressure. This approach enhances air quality and temperature control in remote working zones.

Auxiliary fans feature quick-connect flanges and portable mounting frames for rapid redeployment. Integrated vibration and temperature monitoring enable predictive maintenance, reducing downtime and ensuring continuous safe airflow.
