The FK3G450-4AAY-30 is a heavy-duty EC backward centrifugal fan built for large-scale industrial ventilation. Operating at 380VAC (three-phase, 50/60Hz) with 1000W power, it delivers a massive 7700 m³/h airflow and 665 Pa static pressure—ideal for grain conveying, factory HVAC, and data centers. Its IP54 protection, die-cast aluminum construction, and Class F insulation ensure durability in harsh, high-demand environments.
• Massive Airflow Output: 7700 m³/h (4531.45 CFM) airflow covers large spaces (e.g., 1000㎡ warehouses) with 8–10 air changes per hour.
• Three-Phase Power Stability: 380VAC three-phase input (range: 304–456VAC) ensures consistent performance, even in voltage-fluctuating industrial grids.
• Smart Integration: Supports 0–10VDC/PWM speed control and RS485 Modbus for automated systems; FG tachometer (5 pulses/rev) and alarm contacts enable real-time fault monitoring.
• Grain Conveying Ventilation: Removes moisture and dust from grain processing plants, preventing mold growth and ensuring grain quality—IP54 resists grain dust ingress.
• Large-Scale Industrial HVAC: Boosts airflow in factory duct systems or warehouse exhausts, regulating temperatures for machinery and workers in 24/7 operations.
• Data Center Airflow Management: Cools server racks in large data centers, with high airflow ensuring heat is dissipated evenly across multiple cabinets.
• Nominal Voltage: 380VAC (three-phase, range: 304–456VAC)
• Current Draw: 1.67±10% A
• Speed: 1450±5% RPM (low speed for high airflow, reducing noise vs. high-RPM fans).
• Power Consumption: 1000±10% W
• Insulation Class: Class F (withstands up to 155°C, higher than standard Class B).
• Impeller: 450mm diameter, galvanized steel (heavy-duty for continuous grain dust exposure; resists corrosion).
• Motor: BLEC137 external-rotor EC (high torque for moving large air volumes; 50,000-hour L10 lifespan).
• Protection: IP54 (prevents dust accumulation and low-pressure water jets—critical for grain plants).
• Sound Pressure Level: 80±5 dB(A) (manageable for industrial settings with proper ducting).
• Safety Features: Motor current limitation, over/undervoltage shutdown, and thermal overload protection.
• MODBUS Configuration: Custom protocol setup for integrating with factory automation systems (e.g., SCADA).
• On-Site Installation: Professional installation for bulk orders (e.g., grain processing plants) to ensure optimal airflow.
• Maintenance Plans: Annual inspection and bearing lubrication services to extend fan lifespan beyond 50,000 hours.
