Explosion-proof centrifugal fans employ backward-curved or radial impellers within Ex d motor enclosures, preventing internal sparks from igniting external atmospheres.
These fans deliver airflow from 1,000 to 200,000 CFM at static pressures up to 8 kPa, making them suitable for ducted ventilation and process exhaust in hazardous areas.
Integrated VFDs in explosion-proof housings provide soft-start and precise speed control based on real-time pressure and gas sensor inputs, optimizing safety and energy use.
Robust steel or alloy construction, sealed bearings, and split-casing access for impeller maintenance ensure long-term reliability in the most demanding hazardous environments.
