Ultra-Large FRP Industrial Centrifugal Fans – Keruite Product Introduction

About this video

Keruite Air Conditioning Group presents our ultra-large FRP (Fiberglass Reinforced Plastic) industrial centrifugal fans, engineered for the most demanding corrosive air-moving applications. These heavy-duty fans are specifically designed to handle aggressive gas streams including acid fumes, salt-laden air, chlorine emissions, and other caustic vapors that would quickly corrode conventional metal fans. By combining fiberglass reinforcement with advanced thermoset polymers, our FRP fan housings and impellers achieve exceptional chemical resistance while remaining virtually impossible to dent or crack. Product Overview Our ultra-large FRP centrifugal fans feature a robust construction comprising impeller, housing, air inlet, motor, bearing assembly, belt drive system, and vibration isolators. Each unit is performance-tested in accordance with AMCA (Air Movement and Control Association) Standard 210-99, with vibration levels complying with ISO 2372 G4.5 grade specifications. The fans have achieved China Energy Conservation Certification Grade 1 standards and are recognized as one of the earliest Chinese FRP fan products to obtain AMCA certification. Key Technical Specifications Airflow Capacity: Up to 100,000 CMH (standard models), with select configurations reaching up to 320,610 m³/h for the largest industrial applications Static Pressure: Capable of achieving pressures up to 3,250 Pa or higher, with certain models reaching up to 5,500 Pa Temperature Resistance: Operating temperatures up to 80°C standard, with specialized designs available for higher temperature requirements Motor Power Range: 1.1 kW to 560 kW, accommodating diverse industrial requirements Rotational Speed: 960 to 2,900 RPM depending on model and application Drive Configurations: Available in belt-driven (C-type), direct-drive (A/D-type), and coupling configurations to suit specific installation requirements Size Range: Fan numbers from #4 to #16, with customizable dimensions available Superior Construction Features All-FRP Airstream Components: Fan housing, inlet cone, and impeller are fabricated entirely from pure FRP, eliminating the corrosion vulnerabilities found in traditional carbon steel with FRP lining Advanced Composite Resins: Fire-retardant polyester or epoxy resins available, meeting Class 1 flame ratings for added safety in explosive atmospheres Corrosion-Resistant Fasteners: Bolts connecting housing to frame utilize integrated molding encapsulation, completely eliminating bolt corrosion issues Precision-Balanced Impellers: Dynamically and statically balanced to class 4.0 grade (national standard), ensuring smooth operation, high aerodynamic efficiency, and low noise Double-Layer Base Design: Facilitates maintenance without removing foundation bolts, simplifying service procedures Specialized Shaft Sealing: Custom shaft seal treatment prevents leakage of toxic or hazardous gases Seamless Bonding Technology: Volute casing features seamless adhesive bonding for superior sealing and leak prevention Typical Applications Chemical Processing: Exhausting acid fumes, solvents, and reactive chemical vapors PCB Manufacturing & Electronics: Ventilation for etching, plating, and cleanroom environments Pharmaceutical Industry: Corrosive gas handling and cleanroom ventilation Metal Processing & Plating: Fume exhaust for electroplating, pickling, and surface treatment lines Wastewater Treatment: Odor control and corrosive gas extraction Semiconductor Manufacturing: Process ventilation for cleanroom and fab facilities Petrochemical: Handling aggressive gas streams in refining and processing environments Why Choose Keruite Ultra-Large FRP Centrifugal Fans? Superior Corrosion Resistance: FRP construction withstands sulfuric, nitric, hydrochloric acids, ammonia, and other caustic substances far longer than stainless steel or aluminum fans Exceptional Efficiency: Higher fan efficiency translates to lower rotational speeds, extending component life and reducing operational costs Cost-Effective Alternative: Compared to exotic alloy fans, FRP fans deliver comparable longevity at significantly lower cost, requiring fewer rebuilds over service life Low Maintenance: No rusting means bearings and shafts remain cleaner; reduced maintenance frequency and lower total cost of ownership Quiet Operation: Well-balanced impellers and rigid housings ensure smooth, low-noise performance Custom Engineering: Tailored solutions available for specific airflow, pressure, temperature, and dimensional requirements Quality Assurance: ISO9001 certified manufacturing with comprehensive testing before shipment Have a corrosive air handling project requiring ultra-large FRP centrifugal fans?
