The FD3G146-48GL-90 is a dual-inlet centrifugal DC fan engineered by Fanova (Suzhou) Motor Technology for applications requiring balanced airflow and compact efficiency. Powered by a brushless DC motor (BLDC92), it operates on 48V DC systems and excels in low-noise environments. With its dual-inlet design and galvanized steel impeller, it delivers reliable performance for embedded cooling solutions while meeting CE, RoHS, and ErP2015 standards.
Dual-Inlet Efficiency & Balanced Airflow
Features dual air intakes for enhanced airflow symmetry, generating 1,200 m³/h max airflow and 425 Pa static pressure at 1,700 RPM. Ideal for space-constrained installations requiring uniform cooling.
Low-Noise DC Operation
Optimized for quiet performance at 66 dB(A)—suitable for noise-sensitive environments like medical devices or laboratories. Runs on 48V DC (36–57V range) with PWM/0–10VDC speed control.
Robust Industrial Build
Constructed with a galvanized steel impeller (38 blades), die-cast aluminum housing, and ball bearings. IP44-rated for dust/splash resistance and operates from –25°C to 60°C with 50,000-hour lifespan (L10).
Simplified Integration
Minimal wiring: +48VDC input, PWM control, FG tachometer (4 pulses/revolution), and GND. Compact 146mm impeller fits confined spaces without sacrificing airflow.
Electronics Cooling: Servers, telecom cabinets, and power supplies.
Medical Equipment: Ventilation for imaging devices or lab analyzers.
Renewable Energy Systems: Cooling inverters in solar/wind power installations.
Q1: Can this fan run on AC power with an adapter?
A1: No. It requires a 48V DC power source (36–57V range). Use a compatible DC power supply or battery system.
Q2: Is the FG signal compatible with standard tachometers?
A2: Yes. The FG wire outputs 4 pulses per revolution and works with +5V or +12V tachometers (max. pull-up current: 1.1mA).
Q3: Does the dual-inlet design improve airflow efficiency?
A3: Absolutely. Dual inlets reduce turbulence and evenly distribute air intake, lowering noise and vibration versus single-inlet designs.
