The FB3G280-85PL-20 is a high-efficiency backward-curved DC centrifugal fan designed for industrial ventilation systems requiring balanced airflow and pressure performance. Operating at 85VDC (68-102V range), it delivers substantial airflow (3084 m³/h) while maintaining moderate noise levels (78 dB(A)). Its reinforced plastic-fiber impeller and versatile mounting options make it ideal for demanding applications from HVAC systems to industrial equipment cooling.
Optimized DC Performance
Engineered for 85VDC systems, providing efficient operation at 2610 RPM with 777 Pa static pressure output. Integrated voltage monitoring ensures stable performance in fluctuating power environments.
Balanced Airflow Design
6-blade reinforced plastic impeller (280mm diameter) optimizes the pressure-to-noise ratio, delivering 3084 m³/h airflow suitable for medium-resistance systems.
Industrial-Grade Construction
IP44-rated against dust/moisture ingress. Withstands -25°C to 60°C extremes with ball bearings and die-cast aluminum housing for 50,000-hour continuous operation.
Smart Control Integration
Standard 0–10VDC/PWM speed control + FG tachometer output (3 pulses/revolution) for real-time RPM monitoring. Pre-wired with 20AWG cables for simplified installation.
Industrial Ventilation: Factory floor air exchange systems
Commercial HVAC: Medium-pressure ducted units
Process Cooling: Machinery, generator enclosures
Air Filtration Systems: Dust collection units, cleanroom applications
Q: Is this compatible with 24V or 48V DC systems?
A: No. It requires 68-102VDC input. Using lower voltages may trigger under-voltage protection.
Q: How does the tachometer (FG) signal work?
A: The white wire outputs 3 pulses per revolution for speed monitoring by control systems.
Q: Can it operate in high-humidity environments?
A: Yes. IP44 rating protects against moisture ingress in environments up to 90% RH.
Q: What maintenance is required?
A: Sealed ball bearings provide maintenance-free operation for the rated 50,000-hour lifespan.
