The FB3G310-24AL-90 is a low-voltage DC centrifugal fan engineered for quiet, efficient cooling in sensitive environments. Featuring an aluminum impeller and brushless DC motor (BLDC92), it delivers 2050 m³/h airflow at just 67 dB(A). Its 24VDC operation makes it ideal for electronics cooling and applications requiring low-noise ventilation.
Low-Voltage DC Operation
Optimized for 24VDC systems (16-28V range), drawing 5.6A current for safe integration with control circuits and battery-powered setups.
Quiet High-Efficiency Design
Aluminum impeller (310mm, 6 blades) balances 2050 m³/h airflow and 490 Pa pressure at exceptionally low noise (67 dB(A)).
Industrial Durability
IP44-rated housing withstands dust/moisture. Operates in -25°C to 60°C extremes with ball bearings supporting 50,000-hour lifespan.
Precise Speed Management
0–10VDC/PWM control input + FG tachometer output (4 pulses/revolution) for real-time RPM monitoring.
Electronics Enclosures: Servers, telecom cabinets
Medical/Lab Equipment: Imaging devices, diagnostic tools
Low-Voltage Systems: Solar-powered ventilation, mobile units
Quiet Environments: Recording studios, offices
Q: Is this compatible with 12V systems?
A: No. Requires 16–28VDC input. Lower voltages may trigger under-voltage protection.
Q: How quiet is 67 dB(A) in practice?
A: Comparable to background office noise—ideal for noise-sensitive spaces.
Q: Can it handle outdoor conditions?
A: Yes. IP44 rating protects against rain splashes and dust in covered outdoor installations.
Q: What's the advantage of aluminum impellers?
A: Better heat dissipation and durability vs. plastic alternatives in high-RPM applications.
