The FB3G400-2AAP-20 is a heavy-duty EC centrifugal fan engineered for high-pressure industrial air handling. Featuring a die-cast aluminum impeller and integrated RS485 Modbus interface, it delivers robust airflow up to 4,494 m³/h while resisting mechanical stress in harsh environments. Certified to IP54, CE, and ErP standards, it excels in ventilation systems requiring precise control and fault monitoring.
Industrial Pressure Master
Generates 604 Pa static pressure with backward-curved blades — ideal for overcoming duct resistance in filtration systems or long-distance airflow.
Smart Connectivity Ready
Native RS485 Modbus support (RSA/RSB wires) enables direct integration with PLCs/BMS for real-time speed adjustment and diagnostics.
Metal-Core Durability
Full aluminum construction (impeller + housing) withstands impacts and high temperatures up to 60°C — 3x longer lifespan vs plastic fans.
Proactive Safety Monitoring
Dedicated alarm contacts (NC/COM) trigger external alerts for overheating or RPM failure — critical for unattended operations.
Industrial Process Ventilation: Fume extraction, powder conveying, drying tunnels.
High-Resistance Systems: HEPA filter bypass, compact duct networks.
Automated Facilities: Smart factories, cleanrooms with centralized control (Modbus).
Hazardous Environments: Foundries, chemical plants (IP54 dust/moisture resistance).
Q: Why choose aluminum over plastic impellers?
A: For high-RPM stability — reduces deformation at 1,500 RPM and resists abrasive particles.
Q: Can I ignore the orange/gray (alarm) wires?
A: Yes, but connecting them to a relay enables automatic shutdown during faults (e.g., motor jam).
Q: Is Modbus mandatory for speed control?
A: No — use 0-10V/PWM (yellow wire) for basic control. Modbus adds diagnostics like temperature logging.
Q: Why "backward" centrifugal design?
A: Delivers 30% higher pressure at lower noise (76.9 dB(A)) vs forward-curved blades.
