The FK3G310-48AY-21 is a compact DC centrifugal fan engineered for efficient ventilation in space-constrained applications. Powered by a brushless DC motor (BLDC102), it delivers moderate airflow up to 3020 m³/h (1777 CFM) and static pressure up to 665 Pa (2.66 in.wg). Designed for flexible integration, it operates across a wide DC voltage range (36–57 VDC) and features simplified wiring for easy installation in diverse environments.
DC Voltage Versatility & Efficiency
Optimized for 48VDC systems (compatible with 36–57VDC), it consumes only 336W (±10%) at full load, making it ideal for battery-powered or low-energy setups like mobile equipment or solar-powered ventilation.
Quiet Mid-Range Performance
Generates just 69 dB(A) noise at 2200 RPM (±5%), balancing airflow (3020 m³/h) and acoustic comfort for noise-sensitive indoor applications.
Compact & Durable Build
Features a 310mm aluminum impeller, IP44-rated housing for dust/moisture resistance, and ball bearings for reliable continuous operation (50,000-hour L10 life at 40°C).
Electronics Cooling: Server racks, telecom cabinets, and power converters.
Portable Ventilation Systems: Medical devices, mobile labs, or portable HVAC units.
Light Industrial Equipment: 3D printers, laser cutters, or small-scale fume extraction.
Renewable Energy Integration: Solar/battery-backed ventilation in off-grid installations.
Q: Can this fan run on unstable DC power sources (e.g., solar/battery)?
A: Yes, its wide voltage range (36–57VDC) tolerates fluctuations common in renewable energy systems.
Q: Is PWM speed control supported?
A: Yes, standard 0–10VDC or PWM input allows precise RPM adjustment (no built-in RS485).
Q: What distinguishes it from higher-power centrifugal fans?
A: Its compact size (310mm impeller), lower noise (69dB), and DC focus suit applications where space/energy efficiency outweighs extreme airflow needs.
Q: Is the wiring compatible with basic controllers?
A: Yes—only 4 wires: +48VDC (red), PWM control (yellow), FG tachometer (white), and ground (blue).
