mine flameproof fan

Mine flameproof fans are designed for environments containing methane or combustible dust, with flameproof (Ex d) enclosures that prevent internal ignition sources from causing external explosions. These fans are pivotal in maintaining safe airflow in underground workings.

Constructed from abrasion-resistant alloys and featuring anti-spark impeller rings, they deliver up to 200,000 CFM at static pressures to 6 kPa. Sealed-for-life bearings and robust housings ensure continuous, low-maintenance operation.

Variable frequency drives (VFDs) integrated into Ex d enclosures provide soft-start functionality and adaptive speed control based on gas, temperature, and vibration sensors. This dynamic control enhances safety and optimizes energy use.

Modular components and split-casing designs simplify servicing. Mine flameproof fans meet MSHA, ATEX, and IECEx standards, offering reliable and compliant ventilation in the harshest mining conditions.
