Explosion-proof contra-rotating fans feature two counter-spinning impellers on a single shaft, recovering swirl energy to boost static pressure by up to 20% over single-stage designs. The Ex d flameproof enclosure prevents any internal sparks from igniting external atmospheres, making them ideal for methane- or dust-prone applications.
The first impeller generates velocity and swirl; the second straightens the flow, converting kinetic energy into pressure. This dual-stage approach delivers high-pressure airflow—in the range of 20,000–80,000 CFM at up to 4 kPa—within a compact footprint.
Premium IE4 motors and explosion-proof variable frequency drives (VFDs) enable adaptive ventilation, adjusting speed based on real-time gas, temperature, and vibration sensors. Soft-start capability reduces mechanical stress, while integrated diagnostics support predictive maintenance.
Maintenance is simplified by split-casing for impeller access, sealed-for-life bearings, and external lubrication points. These fans deliver safe, reliable, and energy-efficient airflow in the harshest hazardous-area environments.
