The FB3G310-24AY-90 is a heavy-duty 24V DC centrifugal fan engineered for high-torque, low-noise cooling in mobile and industrial applications. Featuring a robust 310mm aluminum impeller, it delivers massive airflow (2,150 m³/h) at surprisingly quiet 64 dB(A) – ideal for environments where power efficiency and noise sensitivity coexist. Built to endure harsh conditions (IP44, -25°C to 60°C), it excels in electric vehicles, mobile machinery, and renewable energy systems.
24V DC High-Torque Performance
Optimized for battery/solar systems (16–28V DC), delivering 480 Pa static pressure to overcome resistance in compact ducts or filtration setups.
Maintains stable output even with voltage fluctuations common in mobile applications.
Large-Impeller Quiet Operation
310mm aluminum blades move 2,150 m³/h air at just 1,600 RPM, reducing noise by 30% vs. comparable industrial fans.
Precision-balanced rotor (G6.3) minimizes vibration for vibration-sensitive equipment.
Plug-and-Play Industrial Controls
Simplified 4-wire interface supports 0–10V DC or PWM speed control with high-resolution tachometer (4 pulses/revolution).
Reverse-polarity protection prevents damage from wiring errors during field installations.
Electric Mobility: Battery/power electronics cooling in EVs, buses, and charging stations.
Mobile Machinery: Ventilation for construction equipment, agricultural vehicles, or marine engines.
Off-Grid Energy: Cooling in solar inverters, battery storage containers, and generator sets.
Industrial Cabinets: High-flow exhaust for telecom shelters or server enclosures.
Q1: Can it run directly from vehicle batteries without a voltage regulator?
A1: Yes. Its wide voltage range (16–28V DC) tolerates fluctuations in 24V automotive/off-grid systems.
Q2: Why choose aluminum impellers for mobile applications?
A2: Aluminum withstands vibration/shock better than plastic, ensuring longevity in rough terrains.
Q3: How does the FG signal help in automation?
A3: The 4-pulse/rev output enables precise RPM monitoring for predictive maintenance or system alerts.
