mining explosion-proof fan

Mining explosion-proof fans are essential for underground coal and metal mines where methane or combustible dust poses ignition risks. Certified to Ex d IIB T4 standards, these fans prevent internal sparks from triggering external explosions.

Heavy-duty steel casings and copper-aluminum impeller rings resist impact and prevent friction sparks. Impeller configurations—axial or centrifugal—deliver airflow up to 200,000 CFM at static pressures to 6 kPa.

Variable frequency drives (VFDs) in flameproof enclosures enable soft-start and adjustable speed, matching ventilation to production demands and reducing wear. Temperature and vibration sensors provide early warning of mechanical issues.

Split-casing designs and quick-release access panels simplify inspection and service. These fans ensure continuous, safe ventilation in the most hazardous subterranean environments.
