FK3G310-4AAS-30
Fanova
The FK3G310-4AAS-30 is a heavy-duty 380V EC centrifugal fan designed for extreme industrial ventilation and high-pressure cooling applications. Featuring a 310mm aluminum impeller and advanced EC motor technology, this three-phase fan delivers unparalleled performance with a maximum airflow of 4514 m³/h (2656.49 CFM) and a powerful 958 Pa static pressure. It is engineered to meet the demanding operational requirements of harsh environments, including foundries, chemical plants, and large-scale HVAC systems.
With an 850W rated power, IP54 protection level, and Class F insulation, this industrial centrifugal bracket fan combines rugged construction with smart control capabilities. The integrated support bracket ensures stable mounting in heavy-industry settings, while the 50,000-hour working life (L10 at 40℃) and comprehensive safety features make it a reliable choice for critical infrastructure and high-resistance scenarios.

This three-phase centrifugal fan generates 958 Pa static pressure and 4514 m³/h airflow, making it ideal for applications requiring massive air displacement against high resistance—such as ducted industrial systems, dust collection units, and industrial ovens. The 8-blade galvanized steel impeller is optimized for high static pressure and reduced turbulence, handling abrasive particulates better than composite blades in heavy-industry environments.
Designed for 380VAC three-phase power systems, the fan supports 0~10VDC/PWM speed modulation for precise airflow control. It features RS485 MODBUS connectivity, enabling seamless integration into automated industrial networks (BMS/PLC systems) for real-time monitoring and remote control. The FG tachometer output (5 pulses/rev) provides accurate speed feedback for system optimization.
With an IP54-rated housing, the fan resists dust and water ingress, ensuring reliability in harsh industrial conditions. Class F insulation enhances heat resistance, while integrated alarm contacts (NC/COM) enable predictive maintenance. Safety features include soft-start sequencing, under/over voltage detection (304~456VAC), thermal overload cutoffs, reverse polarity protection, and locked-rotor protection, ensuring fail-safe operation in unstable power environments.
Perfect for foundries, chemical processing plants, and heavy machinery cooling, where high airflow and pressure are required to dissipate extreme heat. The fan’s rugged construction and abrasive-resistant impeller handle harsh industrial contaminants effectively.
Ideal for large-scale commercial and industrial ventilation systems, including office complexes, factories, and warehouses. It provides powerful air displacement for ductwork networks, improving overall HVAC efficiency and indoor air quality.
Suitable for turbine cooling and transformer heat dissipation in power plants, where reliable heat removal is critical for equipment performance and longevity. The fan’s high static pressure overcomes the resistance of cooling systems in power generation infrastructure.
Excels in dust collection systems, industrial ovens, and high-resistance ductwork, where standard fans struggle to maintain airflow. The 958 Pa static pressure ensures consistent performance even in systems with dense filters or long duct runs.
This fan is specifically designed for 380VAC three-phase power systems (304~456VAC range) at 50/60Hz. It is not compatible with single-phase power, as its performance and control features rely on three-phase electrical input.
Use the green (RSA) and purple (RSB) wires for RS485 communication. This enables seamless integration with industrial BMS/PLC systems, allowing real-time monitoring of speed, airflow, and operational status, as well as remote speed control.
The 8-blade aluminum (galvanized steel sheet) impeller is optimized for high static pressure and reduced turbulence. It is more durable than composite blades, handling abrasive particulates common in heavy-industry environments (e.g., foundries, dust collection) without wear or degradation.
The +10VDC output is limited to 1.1mA, making it suitable only as a pull-up voltage for tach signals. It cannot power external sensors or accessories—always use a series resistor when connecting to tachometer inputs to avoid electrical damage.
