The FS3G120-48GL-70 is a compact DC centrifugal fan engineered for precision cooling in space-constrained electronic systems. Powered by a 48VDC brushless motor (BLDC72) with a galvanized steel impeller (120mm), it delivers 310 m³/h (182 CFM) airflow at 340 Pa (1.36 in.wg)—exceptional pressure for its size. Designed for embedded applications, its IP44-rated housing and ultra-quiet 65 dB(A) operation make it ideal for noise-sensitive environments.
High-Pressure Miniature Design
Generates 340 Pa static pressure—unprecedented for 120mm fans—enabling effective cooling in dense PCB arrays or sealed enclosures with restricted airflow paths.
Low-Noise DC Operation
Optimized 34-blade impeller and precision balancing achieve 65 dB(A) at 2,580 RPM—20% quieter than comparable DC fans—while consuming only 67W.
Plug-and-Play Integration
Simplified 4-wire control:
Red: +48VDC input
Yellow: 0–10V/PWM speed control
White: FG tachometer (2 pulses/revolution)
Blue: Ground
Reduces wiring complexity in multi-fan systems.
Server/GPU Cooling: High-pressure cooling for RAM modules or VRMs in data centers.
Medical Imaging Devices: Vibration-sensitive cooling in MRI/CT scanner electronics.
Telecom Base Stations: 5G RRU (Remote Radio Unit) temperature management.
Laboratory Analyzers: Compact fume extraction in benchtop instruments.
Q1: Why choose galvanized steel over plastic impellers?
A1: Steel maintains blade rigidity at high RPMs, preventing flex that causes noise/vibration—critical for precision instruments.
Q2: Can it run on battery power?
A2: Yes. Compatible with 36–57VDC sources (e.g., 4x 12V batteries), drawing only 1.4A at full load.
Q3: How does IP44 protect against dust?
A3: Sealed electronics resist 1mm+ particles—sufficient for indoor industrial settings. Avoid direct water jets.
Q4: Is the tachometer signal essential?
A4: FG output enables real-time RPM monitoring for predictive maintenance—recommended for critical systems.
