underground explosion-proof fan

Underground explosion-proof fans are essential for safe ventilation in methane-bearing coal mines or dust-prone metal mines. Their Ex d flameproof motor housings prevent sparks from igniting explosive atmospheres.

Available as high-capacity axial or centrifugal units, these fans move 20,000–200,000 CFM at up to 6 kPa static pressure. Heavy-gauge steel construction and balanced impellers ensure durability under continuous duty.

Integrated VFDs enable adaptive ventilation, modulating fan speed to maintain target airflow based on real-time sensor data for gas concentration and airway pressure, improving safety and reducing energy consumption.

Split-casing for impeller access, external lubrication points, and remote diagnostic capabilities simplify maintenance and maximize uptime, ensuring reliable, compliant underground ventilation.
