The FB3G310-48PK-20 is a compact DC centrifugal fan engineered for efficient airflow in space-constrained applications. Featuring a lightweight glass-reinforced plastic impeller and brushless DC motor (Model BLDC102), it delivers 2320 m³/h max airflow at 48VDC while operating at low noise levels (69 dB(A)). Designed with IP44 protection and flexible 0–10VDC/PWM speed control, it suits commercial and light industrial cooling systems where energy efficiency and quiet operation are critical.
Low-Voltage DC Efficiency
Optimized for 48VDC power (36–57VDC range), consuming only 150W at 1520 RPM. Integrates reverse polarity protection and soft-start technology for reliable operation.
Lightweight & Low-Noise Design
Plastic + fiberglass impeller reduces weight (total 4kg), enabling quieter performance (69 dB(A)) ideal for noise-sensitive environments like labs or offices.
Flexible Speed Control
Supports 0–10VDC or PWM input for precise RPM adjustment. Includes tachometer output (FG signal: 3 pulses/revolution) for real-time monitoring.
Rugged Build for Continuous Use
IP44-rated housing resists dust/water splashes. Rated for 50,000 hours (L10) at 40°C and operates from –25°C to 60°C.
IT/Telecom Equipment: Cooling servers, routers, and power cabinets.
Medical Devices: Ventilation for imaging machines or diagnostic tools.
Commercial HVAC: Auxiliary airflow in ductless systems or air purifiers.
Transportation: Thermal management in electric vehicle charging stations.
Q1: Can it run on battery power?
A: Yes. The 36–57VDC range supports battery/solar applications.
Q2: Is the plastic impeller durable?
A: Yes. Glass-fiber reinforcement ensures impact resistance and longevity.
Q3: How is the FG signal used?
A: The white wire outputs 3 pulses/revolution—connect to a tachometer for RPM monitoring.
Q4: What certifications apply?
A: CE, RoHS, ISO9001, and ErP 2015 compliant.
