Product Description

4-72 Series Industrial Fume Extractor Fan for Welding and Smoke Removal

The 4-72 Series Industrial Fume Extractor Fan is a high-performance centrifugal ventilation solution designed to effectively remove fumes, smoke, and airborne contaminants generated in industrial environments. Specifically engineered for welding shops, fabrication facilities, and other heavy-duty applications, this fan delivers powerful airflow and efficient fume extraction to maintain clean and safe working conditions.

Crafted with precision using high-quality steel, the 4-72 Series fan features backward-curved blades that ensure stable airflow, low vibration, and long-lasting durability. Its compact structure and versatile mounting options (wall, floor, or ducted systems) make it suitable for a wide range of industrial settings. With high static pressure capabilities, it can handle complex duct networks while maintaining consistent exhaust performance.

Ideal for welding fume extraction, soldering smoke removal, and general air purification tasks, this fan ensures compliance with occupational safety standards and improves indoor air quality. The fan is also compatible with various filtration systems, including carbon and HEPA filters, for enhanced air purification.
