flameproof fan

Flameproof fans utilize heavy-duty Ex d enclosures that contain any internal arcs or sparks, preventing ignition of the surrounding atmosphere. They are essential for safe ventilation in petrochemical plants, grain silos, and mines.

These fans employ backward-curved or axial impellers crafted from anti-spark alloys, delivering airflow up to 150,000 CFM at static pressures up to 4 kPa. Robust housings resist corrosion and mechanical wear.

Optional variable frequency drives (VFDs) enable precise airflow control and soft-start operation, reducing inrush currents and extending component life. Integrated sensors for temperature, vibration, and motor load support predictive maintenance.

With ATEX, IECEx, and MSHA certifications, flameproof fans ensure compliant, continuous operation in hazardous-area ventilation applications.
