The FB3G280-48PL-90 is a high-capacity 280mm DC centrifugal fan engineered for heavy-duty industrial ventilation. Powered by a robust 48V DC brushless motor (BLDC92), it delivers exceptional static pressure and airflow within a wide voltage range (36–57V DC). Featuring a lightweight glass-fiber-reinforced plastic impeller and IP44-rated die-cast aluminum housing, it meets CE, RoHS, ISO9001, and ErP 2015 standards for demanding environments.
Industrial-Grade Pressure Performance:
Generates 661 Pa max static pressure at 2,286 m³/h airflow—ideal for overcoming high resistance in ducted systems or dense filtration setups.
Optimized Impeller Design:
6-blade plastic-fiberglass composite reduces weight while maintaining structural integrity, enabling efficient operation at lower noise levels (69.9 dB(A)).
Precision Speed Management:
Supports PWM/0–10VDC speed control and provides FG tachometer output (4 pulses/revolution) for real-time RPM monitoring and system integration.
Extended Operational Resilience:
Built-in protections (reverse polarity, thermal overload, motor lock) ensure reliable performance in unstable power conditions across -25°C to 60°C.
Heavy Industrial Ventilation: Fume extraction in welding facilities, foundries, and chemical plants.
Large-Scale HVAC: Air handling units (AHUs), duct pressurization in commercial buildings.
Power Generation: Cooling for transformer cabinets, generator enclosures, and battery rooms.
Material Handling: Dust collection systems and pneumatic conveyor exhausts.
Q: Is the impeller suitable for high-temperature environments?
A: Yes—it operates reliably up to 60°C ambient temperature with ball-bearing durability.
Q: Can the fan be mounted vertically?
A: Absolutely—its ball-bearing motor supports installation in any orientation.
Q: What distinguishes the FG signal output?
A: It delivers 4 pulses per revolution for high-resolution speed feedback.
Q: Is custom wiring length available?
A: Yes—standard power/control leads can be tailored to installation needs.
