The FB3G400-48PK-20 is a high-capacity 400mm diameter centrifugal blower powered by a 250W external-rotor DC motor (BLDC102). Operating on 48V DC (36–57V range), it delivers industrial-grade airflow up to 4,320 m³/h for large-scale ventilation. Its optimized design targets applications requiring substantial air movement at moderate static pressure (445 Pa max), ideal for spacious industrial or commercial environments.
1. Motor & Drive System
Features a direct-drive external-rotor DC motor with ball bearings, eliminating mechanical transmission losses. Engineered for 50,000 hours (L10 life) at 40°C.
2. High-Volume Airflow Performance
Generates 4,320 m³/h max airflow – suited for large spaces. Maintains 445 Pa static pressure to overcome duct resistance in expansive systems.
3. Low-Noise Operation
Runs at 75 dB(A) under full load. Aerodynamically tuned blades minimize turbulence noise, while motor encapsulation reduces electromagnetic interference.
4. Power & Control
Handles 36–57V DC input for unstable power sources (e.g., solar, mobile systems). Supports 0–10V DC or PWM speed control and provides tachometer output (3 pulses/revolution) for real-time monitoring.
5. Protection & Robustness
Includes:
Soft-start, over/under voltage cutoff
Thermal overload protection (motor/electronics)
Locked-rotor and reverse-polarity safeguards
IP44-rated against dust/water splashes
6. Heavy-Duty Construction
Impeller: Glass-fiber reinforced polypropylene
Housing: Die-cast aluminum
Installation: Supports any orientation
Weight: 3,600g (fan), 400g (inlet)
Large-Space Ventilation: Factories, warehouses, or agricultural facilities needing high-volume air exchange.
Industrial Process Cooling: Equipment cooling in manufacturing plants.
Commercial Air Handling Units (AHUs): Moving air through low-resistance duct networks.
Renewable Energy Systems: Solar/wind installations requiring DC-compatible airflow.
