FB4-72 Series FRP Centrifugal Fan with Corrosion-Resistant Construction, High-Efficiency Airfoil Impeller, and Multiple Transmission Options

Professional industrial-grade fiberglass reinforced plastic (FRP) centrifugal fan specifically designed for conveying highly corrosive industrial gases. Entire air-contacting components constructed from premium FRP material providing exceptional resistance to acids, alkalis and chemical corrosion.

• Full FRP Corrosion-Resistant Construction: Casing, impeller and air inlet manufactured from high-quality fiberglass reinforced plastic with excellent resistance to acids, alkalis, salts and most chemical corrosives
• High-Efficiency Airfoil Impeller Design: 10 backward-curved airfoil-shaped blades optimized for maximum airflow efficiency with precision-molded FRP impeller
• Multiple Reliable Transmission Options: A-type (direct drive), C-type (belt drive), D-type (coupling drive), and B-type (belt drive for large models)
• Aerodynamically Optimized Airflow System: Integrally molded FRP air inlet with curved cross-section and optimized spiral casing design
• Comprehensive Configuration Flexibility: 12 standard model sizes, two rotation directions, and eight standard air outlet angles
• Robust & Easy-to-Maintain Design: Integrated frame construction with low maintenance requirements and easily accessible components

• Petroleum & Chemical Industry: Corrosive gas exhaust, process ventilation, acid mist extraction
• Nonferrous Metallurgy: Smelting plant ventilation, corrosive fume extraction
• Electroplating Industry: Acid and alkali mist exhaust, plating tank ventilation
• Wastewater Treatment: Biological tank aeration, odor control systems, gas extraction
• Brewing & Food Processing: Fermentation gas exhaust, plant ventilation
