The FB3G355-4AAS-30 is a high-power industrial EC centrifugal fan designed for heavy-duty ventilation in demanding environments. Operating on 380VAC three-phase power, it delivers exceptional airflow (6560 m³/h) and extreme static pressure (1080 Pa) – ideal for large-scale industrial systems requiring robust performance. Featuring an aluminum impeller and IP54-rated construction, it combines industrial durability with advanced control integration for automated applications.
Industrial-Grade Power
Engineered for 380VAC three-phase operation with wide voltage tolerance (304–456VAC). Generates massive 1080 Pa static pressure for overcoming high resistance in ducted systems or industrial processes.
Smart Motor Control
Integrated RS485 Modbus communication (RSA/RSB ports) alongside standard 0–10V/PWM control. Includes +10VDC output for signal pull-up and FG tachometer (5 pulses/rev) for real-time monitoring.
Heavy-Duty Construction
Full aluminum impeller and housing withstand harsh conditions. IP54 protection resists dust ingress and water splashes, suitable for factories, plants, or outdoor enclosures.
Enhanced Safety Compliance
Exceeds industrial standards with 1800VAC dielectric strength, leakage current protection (≤3.5mA), and alarm contacts (NC/COM) for system fault reporting. Class F insulation ensures reliability at high temperatures.
Industrial Process Cooling: High-pressure ventilation for furnaces, laser cutters, or industrial ovens.
Large HVAC Systems: Air handling units (AHUs), rooftop vents, or duct boosters.
Power Generation: Cooling for transformers, turbine rooms, or backup generator enclosures.
Manufacturing Equipment: Dust extraction, fume removal, or drying tunnels.
Q: Can it run on single-phase power?
A: No. Requires stable 380VAC three-phase supply (50/60Hz).
Q: How is Modbus RS485 implemented?
A: Use RSA (green) and RSB (purple) wires with standard Modbus RTU protocol. Refer to separate communication guide.
Q: What triggers the alarm contact (NC/COM)?
A: Activates during faults: overheat, locked rotor, or power anomaly.
Q: Is harmonic filtering required?
A: Complies with EN 61000-3-2/3-3. For sensitive grids, add external filters if distortion exceeds local standards.
Q: Can the +10VDC output power external sensors?
A: No. Limited to 1.1mA – use only as pull-up voltage for control signals.
