The FW3G300-48PC-90 is a duct-optimized axial DC fan engineered for high-volume ventilation. Featuring a 300mm glass-fiber-reinforced impeller and integrated wall ring, it delivers 2300 m³/h airflow at just 66 dB(A) noise. Powered by a 48V DC motor (BLDC92), it consumes 80W with IP44 protection and operates continuously (S1 duty) in -25℃ to 60℃ environments.
Duct-Ready Airflow Design
The integrated wall ring minimizes turbulence, enabling straight-airflow efficiency for ducts or enclosures with low static pressure (170 Pa).
Lightweight Composite Impeller
5-blade PP+GF construction reduces inertia for faster response while resisting corrosion in humid environments.
Reverse-Rotation Optimization
Anticlockwise spin (viewed toward rotor) simplifies integration in confined spaces where standard clockwise fans cause airflow conflict.
Ultra-Low Power Profile
Draws just 1.7A at 48VDC—ideal for solar/battery systems—with soft-start protection to prevent surge currents.
Cabinet & Tunnel Ventilation: Server racks, control panels, and agricultural tunnels requiring directional airflow.
EV Battery Cooling: Low-static-pressure cooling in electric vehicles/mobile machinery.
Energy-Efficient Exhaust: Parking garages, workshops where 66 dB(A) noise meets strict acoustic standards.
Q1: Why anticlockwise rotation?
A: Allows mirrored installation vs. standard fans. Critical when space constraints prevent duct redesign—verify rotation mark on housing.
Q2: Can the wall ring be removed?
A: No. Its aerodynamic profile is integral to performance. Removal causes 15-20% airflow loss.
Q3: Is plastic impeller durable at 60°C?
A: Yes. Glass-fiber reinforcement ensures stability ≤85°C (electronics limit). Avoid direct UV exposure.
Q4: How to handle wiring for reverse polarity?
A: Blue wire must connect to control GND. Reversing with power (red) triggers protection shutdown.
Q5: Compatible with speed controllers?
A: Yes. Yellow wire accepts 0-10V/PWM. FG output (white) gives 4 pulses/rev for RPM feedback.
