explosion-proof exhaust axial flow fan

Explosion-proof exhaust axial flow fans are designed to expel hot, contaminated air from hazardous areas—such as mines, chemical plants, and processes with combustible gases or dust. Their axial design offers high volumetric flow rates, typically up to 100,000 CFM.

The fan incorporates Ex d flameproof motor enclosures that prevent internal arcs or sparks from igniting the surrounding atmosphere. Impeller blades and housings use anti-spark alloys to further mitigate ignition risk.

Variable frequency drives (VFDs) in explosion-proof housings provide controlled startup and adjustable speed, allowing precise regulation of exhaust airflow based on temperature, gas detection, and process demand. Soft-start capability reduces mechanical stress and extends service life.

Maintenance is simplified via split-housing design, external lubrication ports, and integrated condition monitoring for vibration and temperature. This fan ensures both safety and reliable exhaust performance in the most challenging environments.
