The FK3G450-4AAY-30 is a heavy-duty EC backward centrifugal fan engineered for industrial ventilation systems demanding high airflow and static pressure. Featuring a robust BLEC137 external rotor motor and die-cast aluminum construction, it delivers 7,700 m³/h airflow at 665 Pa static pressure. With IP54 protection, RS485/MODBUS integration, and compliance with CE/RoHS/ErP standards, it excels in harsh environments requiring intelligent control and reliability.
Industrial-Grade Air Performance
Generates massive 7,700 m³/h airflow and 665 Pa static pressure for large-scale ventilation, cooling, or exhaust systems (e.g., factories, warehouses).
Smart Control & Communication
Supports 0–10V/PWM speed control and RS485/MODBUS protocol for seamless integration into automated systems. Includes FG tachometer (5 pulses/revolution) and +10VDC output for signal pull-up.
Enhanced Environmental Resilience
IP54-rated housing resists dust/water ingress. Wide voltage tolerance (304–456V AC) and thermal protections ensure operation in -25°C to 60°C conditions. Ball bearings extend service life to 50,000 hours (L10).
Advanced Safety & Monitoring
Integrated alarm contacts (NC/COM) for fault detection. Protections include soft-start, motor current limitation, over/under-voltage shutdown, and reverse polarity blocking.
Industrial HVAC (duct boosting, exhaust systems).
Process cooling (ovens, furnaces, heavy machinery).
Data center airflow management.
Manufacturing facilities requiring dust/moisture-resistant ventilation.
Q: Can the +10VDC output pin power external sensors?
A: No. It supplies max. 1.1 mA only for signal pull-up (e.g., tachometer). External devices require separate power.
Q: Is MODBUS protocol pre-installed?
A: RS485 wiring is provided, but MODBUS implementation requires custom configuration. Contact technical support for protocol details.
Q: What triggers the alarm contacts (NC/COM)?
A: They close during faults (e.g., overheating, locked rotor), enabling external monitoring systems.
Q: Can this fan replace three-phase AC units directly?
A: Yes. It accepts 304–456V AC 50/60 Hz three-phase input via L1/L2/L3 terminals.
