Product Overview

The FB3G450-4AAY-80 is an industrial powerhouse EC centrifugal fan engineered for extreme-duty ventilation and cooling in large-scale facilities. Featuring a massive 450mm aluminum impeller and robust 380VAC 3-phase motor, it delivers unparalleled airflow (8,400 m³/h) and static pressure (815 Pa) for heavy industrial processes while exceeding standard certifications with Class F insulation and IP54 protection.


Core Features

  1. Extreme Airflow Performance
    Generates colossal 8,400 m³/h airflow—equivalent to cooling large factory floors—through an 8-blade aluminum impeller optimized for high-pressure efficiency at 1,700 RPM.

  2. Industrial 3-Phase Reliability
    Built for 380VAC industrial grids (304–456VAC range) with 1,200W power handling, reducing cabling complexity and voltage drop issues in large facilities vs. single-phase solutions.

  3. Heavy-Duty Resilience
    Combines IP54-rated dust/water resistance with Class F insulation (155°C rating)—critical for steel mills, foundries, or chemical plants where heat and corrosion degrade standard components.

  4. Advanced Industrial Automation
    Integrates RS485 MODBUS (RSA/RSB), +10VDC output, and dry-contact alarms (NC/COM) for predictive maintenance in Industry 4.0 environments.


Applications

  • Heavy Industrial Ventilation: Furnace exhaust, welding fume extraction, mining ventilation shafts.

  • Process Industries: Plastic extrusion cooling, industrial dryer systems, paper mill machinery.

  • Energy Infrastructure: Turbine hall cooling, transformer thermal management, power plant HVAC.

  • Large-Scale Manufacturing: Automotive paint booth ventilation, shipyard exhaust systems.


FAQ

Q: Can it replace multiple smaller fans in ducted systems?
A: Yes—one FB3G450-4AAY-80 delivers airflow equal to 6+ standard 400mm fans, cutting energy use by 25% and maintenance points.

Q: Is the aluminum impeller suitable for corrosive environments?
A: Anodized aluminum resists humidity and mild chemicals. For acidic exposure, request optional marine-grade coating.

Q: How does Class F insulation extend lifespan?
A: Withstands 155°C vs. Class B’s 130°C—critical near high-heat equipment like kilns where ambient temperatures exceed 60°C.

Q: Minimum electrical protection requirements?
A: Use 10A slow-blow fuses per phase; integrate thermal-magnetic breakers for overload protection (refer to §4 wiring diagram).
