Explosion Proof Centrifugal Fan

Our Explosion Proof Centrifugal Fan is engineered to operate safely in areas containing flammable gases, vapors, or combustible dust. As a core safety component for small and mid-sized plants, it provides reliable ventilation while rigorously controlling potential ignition sources such as sparks and excessive heat. Certified to international standards including ATEX, IECEx, and NEC, this fan is a trusted solution for industries such as petrochemicals, pharmaceuticals, paint spray booths, and grain processing.

The fan employs robust explosion-proof methods, featuring Ex d (flameproof) and Ex e (increased safety) protections. It is rated up to Ex d IIB T4 Gb for gases and Ex tD A21 IP65 T130°C for dust, covering most common hazardous conditions. Critical flamepath surfaces are precision-engineered with gaps ≤0.2 mm, widths ≥15 mm, and surface roughness Ra ≤3.2 μm to safely contain internal explosions. Additional safety features include:

Quick-access explosion-proof inspection panels

Anti-loosening bolts and sealed joints to prevent gas ingress

Spark-resistant copper-alloy fan blades with aluminum hubs

Static grounding points (resistance ≤4 Ω) and anti-static coatings to eliminate electrostatic hazards

The explosion proof centrifugal fan maintains a surface temperature below 100 °C, remaining well under the ignition threshold for classified environments. Designed for easy integration and maintenance, it includes dual grounding terminals at the base for secure earthing. Ideal for ventilating solvent vapors such as toluene or xylene in paint production, the fan can be installed outside the hazardous zone, safely drawing air through ducting. Its certified motor and spark-resistant construction ensure that even in fault conditions, flames are fully contained within the housing, providing lasting protection for both personnel and assets.
