Designed for high-volume industrial ventilation, this 450mm backward-curved centrifugal fan by Fanova (Suzhou) delivers massive airflow (up to 7700 m³/h) with optimized efficiency. Powered by a robust three-phase BLDC motor (Model BLEC137) and featuring an 8-blade aluminum impeller, it operates at 1450 RPM for low-noise, high-output performance. With 380V industrial voltage support, IP54 protection, and Class F insulation, it’s engineered for demanding environments requiring reliable, large-scale air movement.
High-Volume Airflow for Industrial Spaces
Generates 7700 m³/h max airflow at lower noise levels (80 dB(A)), ideal for warehouses, factories, or large HVAC systems needing efficient air exchange without excessive sound.
Three-Phase Power & Wide Voltage Tolerance
Supports 380V (304–456V range) three-phase input, reducing energy loss and compatible with global industrial grids. Includes soft-start and phase-loss protection for stable operation.
Extended Durability & Easy Integration
50,000-hour L10 lifespan with ball bearings and -25°C cold-start capability. Offers 0–10VDC/PWM control + RS485 (MODBUS) for seamless automation system integration.
Industrial Safety Compliance
Meets CE, RoHS, ISO9001, ErP 2015 standards. IP54 rating resists dust/moisture ingress, while die-cast aluminum housing ensures mechanical resilience in harsh conditions.
Large-Scale Ventilation: Warehouse air exchange, factory fume extraction.
Commercial HVAC: Air handling units (AHUs) for malls, theaters, or data centers.
Process Cooling: High-flow cooling for industrial machinery or condensers.
Air Curtains/Barriers: Creating separation zones in loading docks or entrances.
Q1: Can this fan run on single-phase power?
No. It requires a three-phase 380V power supply. For single-phase options, refer to Fanova’s FK series (e.g., FK3G280).
Q2: How does it handle voltage fluctuations?
Its wide voltage range (304–456V) and built-in over/under-voltage protection ensure automatic shutdown during surges/drops, preventing damage.
Q3: Is external speed control mandatory?
No. It runs at full speed by default but supports optional 0–10VDC/PWM or MODBUS controls for variable airflow demands.
Q4: Why are all three power wires (L1/L2/L3) black?
Industrial three-phase systems often use uniform wire colors. Follow the wiring diagram strictly: L1/L2/L3 connect to 380V phases, PE (green/yellow) to ground.
