FK3G310-2AAS-30
Fanova
The FK3G310-2AAS-30 is a heavy-duty backward centrifugal fan designed for high-demand industrial ventilation and energy storage battery cabin heat dissipation. Certified by CE, this 230V EC fan features advanced EC motor technology and a 310mm aluminum impeller, delivering exceptional airflow of 4,482 m³/h (2,637.66 CFM) at 933 Pa static pressure. Its robust construction and smart control capabilities make it ideal for harsh environments—from industrial exhaust systems to power equipment cooling—where reliability, energy efficiency, and precise airflow management are non-negotiable.

This high air volume centrifugal fan generates 4,482 m³/h airflow at 933 Pa static pressure, optimized for ducted systems, filtration units, and processes requiring massive air displacement against significant resistance. The 310mm galvanized steel sheet impeller and EC motor work in tandem to deliver consistent performance, making it perfect for energy storage battery cabin heat dissipation and industrial exhaust.
Supports 0~10VDC/PWM speed modulation and RS485 MODBUS communication, enabling seamless integration into building management systems (BMS) and automated industrial networks. The FG (tachometer) output (5 pulses/rev) provides real-time speed feedback, while the intuitive wiring design simplifies setup—critical for centralized monitoring of energy storage cooling systems.
With an IP54 protection rating, this fan resists dust and water ingress, ensuring durability in harsh industrial conditions. Class F insulation stabilizes performance in extreme temperatures (-25℃ to 60℃), while integrated alarm contacts (NC/COM) trigger alerts for faults like motor lock or overload—enabling predictive maintenance and minimizing downtime.
Designed for single-phase 230VAC operation (184~270VAC voltage range), it handles grid fluctuations with ease. Equipped with soft-start protection, voltage fluctuation safeguards, and thermal cutoffs, this CE certificated centrifugal fan ensures fail-safe performance during unstable power conditions—essential for critical applications like energy storage battery cooling.
This energy-efficient centrifugal fan is tailored for high-demand industrial scenarios:
Energy storage battery cabin heat dissipation (optimized for thermal management of battery systems)
Industrial exhaust systems: Fume extraction in welding, chemical processing, and manufacturing
HVAC central units: Ventilation for large commercial buildings and industrial facilities
Process cooling: Temperature control for ovens, furnaces, and industrial dryers
Power equipment cooling: Transformer and turbine heat dissipation
Its high static pressure and airflow make it a reliable solution for confined spaces and ducted ventilation systems.
No. The fan is designed for standard single-phase 230VAC power (50/60Hz), making it suitable for facilities without three-phase infrastructure.
Yes. The RS485 interface (green/purple wires) supports MODBUS protocol integration, enabling centralized monitoring and control of ventilation or cooling systems.
The orange/grey wires (NC/COM) trigger a dry-contact signal during faults (e.g., motor lock, overload), allowing external equipment shutdown or real-time alerts for maintenance.
Limited to 1.1mA—suitable only as a pull-up voltage for tach signals. Always use a series resistor to protect sensors and the fan’s electronics.
