The FK3G400-2AAP-20 is a heavy-duty EC centrifugal fan engineered for large-scale industrial ventilation and high-volume cooling. Featuring a massive 400mm aluminum impeller, robust IP54-rated housing, and advanced control interfaces, it delivers unparalleled airflow capacity (4,494 m³/h) for demanding applications while meeting CE, RoHS, and ErP2015 standards.
Industrial-Grade Airflow Capacity
Generates massive 4,494 m³/h airflow with a 400mm aluminum impeller—ideal for cooling large machinery, warehouse ventilation, or industrial HVAC systems requiring high-volume air movement.
Enhanced Environmental Protection
IP54-rated construction resists dust ingress and water splashes, exceeding standard IP44 ratings for reliability in harsh environments like mining or chemical plants.
Smart Control & Monitoring
Integrates MODBUS-RTU via RS485 (RSA/RSB terminals) for network integration, alongside +10VDC output, FG tachometer (5 pulses/rev), and alarm contacts (NC/COM) for predictive maintenance.
High-Pressure Efficiency
Optimized 6-blade design achieves 604 Pa static pressure at low RPM (1,500±5%), reducing energy consumption (300W) while minimizing turbulence noise (76.9 dB(A)).
Expanded Safety Functions
Includes motor overload alerts via dry-contact alarms and thermal cutoffs (115°C max), enhancing system protection beyond standard reverse-polarity safeguards.
Industrial Ventilation: Factory air turnover, welding fume extraction, kiln cooling.
Power Electronics: Wind turbine nacelles, transformer cooling, high-capacity UPS thermal management.
Process Cooling: Plastic molding machines, industrial ovens, laser cutting systems.
Large-Scale HVAC: Commercial air handlers, data center cooling units.
Q: Can MODBUS commands override local speed control?
A: Yes—MODBUS-RTU (via RSA/RSB) takes priority over 0–10VDC/PWM inputs for centralized automation.
Q: What triggers the alarm contacts (NC/COM)?
A: Contacts open during motor overload/overheat, bearing failure, or locked rotor—connect to PLC for alerts.
Q: Is the aluminum impeller corrosion-resistant?
A: Yes—anodized aluminum withstands humid/salty environments. Optional coatings available for chemical exposure.
Q: Minimum duct size for optimal airflow?
A: Match duct diameter to 400mm impeller; maintain ≤20% area reduction to avoid backpressure losses.
