The FD3G146-310PV-90 is a specialized dual-inlet centrifugal fan designed for high-voltage industrial applications. Operating at 310VDC (248–372V range), it delivers robust airflow (1108 m³/h) while maintaining low noise (63 dB(A)). Its reinforced plastic-fiber impeller and IP44-rated construction ensure reliable performance in demanding environments like industrial automation and heavy machinery cooling.
High-Voltage DC Operation
Optimized for 310VDC systems, reducing current draw (0.7A) while maintaining 294 Pa static pressure. Integrated voltage range monitoring prevents under/over-voltage damage.
Efficient Dual-Inlet Design
38-blade impeller (146mm) maximizes airflow efficiency. Lightweight composite construction (3600g total) reduces inertial load for rapid speed response.
Industrial-Grade Reliability
Withstands -25°C to 60°C extremes and 90% humidity. Ball bearings and die-cast aluminum housing support 50,000-hour continuous operation (L10).
Seamless Control Integration
Standard 0–10VDC/PWM speed control + FG tachometer output (4 pulses/revolution). Pre-wired with 20AWG cables for simplified installation.
High-Voltage Industrial Systems: CNC machines, laser cutters
Power Conversion Equipment: UPS cooling, inverter cabinets
Renewable Energy Infrastructure: Solar/wind power converters
Railway/Tram Traction Systems: Onboard power unit ventilation
Q: Why choose 310VDC over standard 48V models?
A: Reduces current by 85% for equivalent power, minimizing wiring costs and voltage drop in large-scale installations.
Q: Is this compatible with 3-phase AC systems?
A: Requires DC input. Pair with compatible 310VDC power supplies or rectifiers.
Q: How does the tachometer (FG) signal work?
A: The white wire outputs 4 pulses per revolution for real-time RPM monitoring by control systems.
Q: Can it operate in dusty environments?
A: Yes. IP44 rating protects against particulate ingress and moisture splash.
