The FB3G400-4AAL-30 is a high-capacity EC backward centrifugal fan engineered for heavy-duty industrial ventilation. Powered by a robust EC motor (BLEC137) and featuring an 8-blade aluminum impeller (400mm diameter), it delivers extreme airflow (7550 m³/H) at 380VAC while maintaining precision control via dual-mode inputs (0–10VDC/PWM or RS485 Modbus). Designed for continuous operation (S1 duty) with IP54 protection and compliance with CE, RoHS, and ErP 2015 standards.
Industrial-Grade Airflow Performance
Generates 7550 m³/H airflow and 930 Pa static pressure—ideal for large-scale HVAC systems or factory exhaust—while operating efficiently at 1700W (±10%).
Advanced Control Integration
Supports flexible speed modulation via 0–10VDC/PWM or RS485 Modbus (RSA/RSB), with real-time RPM feedback (FG: 5 pulses/revolution) for automated systems.
Heavy-Duty Resilience
Withstands harsh environments (–25°C to 60°C) using die-cast aluminum construction, IP54-rated sealing, and multi-protection safeguards (overvoltage/locked-rotor/thermal overload).
Industrial Ventilation: High-volume air exchange in foundries, welding shops, or chemical plants.
Commercial HVAC: Central air handling units (AHUs) and ducted exhaust systems.
Power Infrastructure: Cooling for transformers, turbine enclosures, or generator rooms.
Process Automation: Integration into smart manufacturing lines via Modbus communication.
Q: Can it operate with unstable grid voltage?
A: Yes—wide voltage tolerance (304–456VAC) ensures stable performance during fluctuations.
Q: How is the RS485 interface used?
A: Connect RSA (Green) and RSB (Purple) wires for Modbus-enabled speed control or system diagnostics.
Q: What safety certifications apply?
A: Complies with EN 60204-1 (electrical safety), ISO 12100 (mechanical safety), and harmonic/EMC standards (EN 61000-3-2/3-3).
Q: Is the +10VDC output externally powered?
A: No—it’s an internal reference voltage (max. 1.1mA) for control signals or FG pull-up.
