The FB3G355-48PK-20 is a high-performance centrifugal DC fan engineered for industrial ventilation requiring a balance of large-scale airflow and moderate static pressure. Featuring a 355mm glass-fiber-reinforced plastic impeller and brushless DC motor (BLDC102), it efficiently moves 3,600 m³/h air at 48VDC while maintaining structural integrity in demanding environments. Ideal for applications where weight reduction and corrosion resistance are critical.
Optimized Airflow-to-Weight Ratio
Glass-fiber-reinforced plastic impeller enables lightweight construction (vs. metal alternatives) while delivering 3,600 m³/h airflow—ideal for overhead mounting or vibration-sensitive installations.
Robust Performance in Harsh Conditions
Operates at -25°C to 60°C with IP44-rated protection against dust/moisture. Ball bearings and reinforced blades ensure 50,000-hour L10 lifespan under continuous duty.
Energy-Efficient Power Management
Achieves high airflow volume at 250W power consumption (48VDC). Integrated soft-start and voltage protection (36–57VDC) prevent damage during grid fluctuations.
Industrial Ventilation: Factory floors, welding exhaust systems, chemical processing plants.
Renewable Energy Infrastructure: Battery cooling for solar/wind farms, hydrogen fuel cell ventilation.
Material Handling: Dust extraction in woodworking, grain silo aeration.
Transportation: EV charging station thermal management, locomotive engine cooling.
Q: Why choose plastic over aluminum impellers?
A: Glass-fiber reinforcement offers 40% weight reduction with comparable strength, plus immunity to corrosion in humid/chemical environments.
Q: How to mitigate 77 dB(A) noise?
A: Use vibration dampers and speed reduction via PWM control (noise drops ~20 dB at 50% RPM). For critical zones, add duct silencers.
Q: Can it handle explosive dust environments?
A: Standard model is non-explosion-proof; request ATEX-certified variants for hazardous areas.
Q: Is the FG signal (3-pulse) compatible with industrial PLCs?
A: Yes—3 pulses/revolution is standard for RPM monitoring in automation systems.
