Methane-proof fans carry certifications—such as Ex d IIB T3—to guarantee safe operation in methane-rich underground environments. They feature flameproof motor enclosures and spark-resistant impeller materials.
These axial or centrifugal fans deliver 10,000–150,000 CFM at static pressures to 5 kPa. Precision balancing reduces vibration, while sealed-for-life bearings handle humid, dusty conditions.
Explosion-proof VFDs provide controlled startup and adjustable speed based on gas sensor feedback, ensuring consistent ventilation and minimizing the risk of over-ventilation or under-ventilation.
Maintenance-friendly split housings and condition monitoring of motor temperature and vibration enable predictive servicing, ensuring continuous compliance with mine safety regulations.
