Product Description

Industrial Fume Extraction Centrifugal Fan—High-Pressure Chemical & Welding Smoke Removal

The Industrial Fume Extraction Centrifugal Fan is engineered to safely capture, filter, and exhaust toxic fumes, smoke, and airborne particulates in demanding industrial settings. Designed for welding shops, chemical plants, laboratories, and manufacturing facilities, this high-performance centrifugal blower delivers exceptional suction power, corrosion resistance, and reliable operation—ensuring compliance with OSHA, NIOSH, and ATEX safety standards.

Built with a heavy-duty backward-curved impeller and reinforced steel housing, this fume extractor generates high static pressure (up to 700 kPa) to overcome duct resistance while maintaining energy-efficient airflow (500–50,000 CFM). Whether removing welding fumes, chemical vapors, or combustible dust, this system provides long-lasting protection for workers and equipment.

Specification

Applications

Factories & Workshops – Removes metal dust, wood chips, and chemical fumes
Commercial HVAC Systems – Air handling units & ducted ventilation
Mining & Construction – Ventilation in confined spaces
Food Processing & Pharmaceuticals – Cleanroom air circulation

Key Configurations

Superior Fume & Smoke Extraction Performance
- High-pressure centrifugal design captures fine particulates (0.3–10 microns) and toxic gases at the source
- Balanced impeller blades minimize turbulence for smooth, high-velocity airflow
- Explosion-proof (ATEX/EX-proof) models available for flammable vapor environments

Rugged Industrial-Grade Construction
- Powder-coated steel casing with optional stainless steel (316L for acid resistance)
- Sealed motor & bearings prevent dust ingress and moisture damage (IP55/IP65 rated)
- Heat-resistant design handles continuous operation up to 80°C (176°F)

Energy-Efficient & Low Maintenance
- Backward-curved wheel reduces power consumption by up to 30% vs. axial fans
- Belt-driven or direct-drive options (0.75–75kW motor range)
- Quick-access panels for filter changes & impeller cleaning
