explosion-proof ventilation fan

Explosion-proof ventilation fans are built to operate safely in classified hazardous areas—such as petrochemical plants, grain handling, and underground mines—by containing any internal ignition sources within flameproof enclosures (Ex d).

The fans use special alloys for impellers and casings to resist sparks from mechanical friction. Motors and electrical components are housed in certified flameproof shells to prevent arcs from igniting surrounding atmospheres.

Variable frequency drives (VFDs) with explosion-proof housings allow precise airflow control and soft-start capability, reducing mechanical stress. Integrated sensors for vibration, temperature, and motor current enable predictive maintenance and fail-safe shutdowns.

Available in axial, centrifugal, and mixed-flow configurations, these fans ensure safe, reliable ventilation where ignition hazards are present.
