coal mine local ventilation fan

Coal mine local ventilation fans provide targeted airflow directly to stopes, drifts, and development headings where primary ventilation cannot reach. They ensure adequate oxygen supply and dilute harmful gases at the work face.

Compact axial or small centrifugal models deliver 2,000–15,000 CFM at pressures up to 3 kPa. Portable mounting frames and quick-release duct connections allow rapid repositioning.

Equipped with IE3 motors and optional variable frequency drives (VFDs), these fans implement demand-based ventilation, ramping up during blasting or diesel operation and throttling back during idle periods to conserve energy.

Rugged housings, sealed bearings, and vibration sensors ensure reliability. Coal mine local ventilation fans are critical for safe, efficient operations in confined underground spaces.
