Explosion-proof axial flow fans employ propeller-style impellers driven by flameproof motor housings (Ex d) to move large volumes of air in environments containing flammable gases or dust. By containing any internal sparks or arcs, these fans prevent ignition of the surrounding atmosphere.
Constructed with anti-spark alloy blades and sealed bearings, they deliver airflow up to 200,000 CFM at moderate pressures, making them ideal for mine shafts, petrochemical plants, and grain handling facilities.
Integrated variable frequency drives (VFDs) enable soft-start capabilities and adaptive speed control based on gas, temperature, or vibration sensors—optimizing energy consumption while maintaining safe ventilation rates.
Maintenance is simplified by external lubrication points, split-casing impeller access, and remote condition monitoring. Explosion-proof axial flow fans provide reliable, compliant air movement where safety is paramount.
