The FG3G450-48PN-20 is a heavy-duty DC axial fan engineered for industrial cooling systems requiring high airflow and robust performance. Driven by a brushless DC motor (BLDC102) and featuring a 450mm reinforced plastic-GF impeller, it excels in harsh environments while offering intelligent control and protection features. Ideal for large-scale thermal management, it combines power, durability, and adaptability.
Industrial-Grade Cooling Power
Moves 5450 m³/h (3207 CFM) of air—enough to cool large machinery or enclosures—with optimized 5-blade aerodynamics and noise levels as low as 63 dB(A).
Extreme Environment Resilience
Operates in -25°C to 60°C temperatures and 5–90% RH humidity with IP44-rated dust/water resistance. Ball bearings and reinforced construction ensure 50,000 hours L10 lifespan.
Smart Control & Safety
Supports 0–10V/PWM speed tuning and tachometer feedback (FG signal). Built-in protections include soft-start, reverse-polarity lock, over/under-voltage cutoff, and thermal overload shutdown.
Flexible Integration
Mounts in any orientation, accepts custom cable lengths, and complies with CE/RoHS/ISO9001/ErP standards for global deployment.
Industrial Equipment: Cooling CNC machines, laser cutters, or power converters.
HVAC Systems: High-volume airflow in commercial/industrial ventilation units.
Energy Storage: Thermal management for battery packs, UPS systems, or solar inverters.
Data Centers: Supplemental cooling for server racks or backup power rooms.
Q: Can it handle dusty or wet conditions?
A: Yes—its IP44 rating protects against dust ingress and water splashes.
Q: How do I adjust fan speed?
A: Use the 0–10V input or PWM signal (yellow wire). The white wire provides real-time RPM feedback (3 pulses/revolution).
Q: What if voltage fluctuates during operation?
A: Built-in safeguards automatically shut down the fan if voltage drops below 36V or exceeds 57V.
Q: Is reverse wiring a risk?
A: Yes—reverse polarity protection prevents damage, but always verify wiring (red: +48VDC, blue: GND).
