The FB3G250-48PL-20 is a high-power centrifugal fan engineered for extreme cooling challenges. Featuring a backward-curved impeller and brushless DC motor (BLDC102), it delivers massive airflow against high static pressure. Built for industrial heavy-duty applications, it balances brute-force performance with intelligent controls.
Industrial-Strength Airflow
Generates 1248 Pa (4.99 In.wg) static pressure—ideal for high-resistance systems—while moving 1941 m³/h (1142 CFM). Optimized 7-blade plastic-GF impeller operates at 3720 RPM for relentless cooling power.
Ruggedized for Demanding Environments
Die-cast aluminum housing and ball bearings withstand vibrations/shocks. IP44-rated against dust/moisture, operating in -25°C to 60°C extremes with 50,000-hour L10 lifespan.
High-Voltage Efficiency
Runs on 48VDC (36–57V range) at 420W, minimizing energy loss in long cable runs. Soft-start protection prevents inrush current surges.
Precision Control & Monitoring
0–10V/PWM speed tuning via yellow wire. Real-time RPM feedback (3 pulses/revolution via FG signal) enables closed-loop thermal management.
Industrial Ovens/Furnaces: High-temperature exhaust and cooling.
Laser Cutters/Welders: Extracting fumes and cooling optics under high resistance.
Power Electronics: Cooling high-density inverters or UPS systems.
Heavy Machinery: Ventilation for mining/agricultural equipment enclosures.
Q: Can it handle ducted systems with long pipes?
A: Yes—its 1248 Pa static pressure overcomes resistance in ducts up to 10m (consult specs for exact curves).
Q: How to reduce 83 dB(A) noise?
A: Use PWM control to lower RPM. Noise drops ~20 dB(A) at 50% speed. Acoustic shrouds available on request.
Q: Is reverse wiring protected?
A: Yes—polarity protection halts operation if red/blue wires are swapped. No damage occurs.
Q: What’s the FG signal’s "3 pulses/revolution" used for?
A: Monitors real-time RPM (e.g., fault detection, speed synchronization across multiple fans).
