flameproof exhaust fan

Flameproof exhaust fans are designed for environments containing flammable gases or dust. Their Ex d motor enclosures prevent any internal sparks or arcs from igniting the surrounding atmosphere, ensuring safe continuous operation.

Often configured as axial flow units, these fans deliver high volumetric airflow—up to 100,000 CFM—at moderate pressures to effectively remove smoke, fumes, and particulates from enclosed spaces.

Explosion-proof variable frequency drives (VFDs) allow soft-start operation and precise speed control based on temperature, gas, or airflow sensors, optimizing energy usage and reducing mechanical stress.

Heavy-gauge steel or stainless steel housings, anti-spark impeller alloys, and sealed bearings resist corrosion and particulate ingress. Split-casing designs and external lubrication points facilitate quick maintenance in demanding applications.
