The FK3G450-2AAY-30 is a high-power backward centrifugal fan engineered for heavy-load industrial ventilation and process cooling. Featuring an EC motor (BLEC137) and 450mm aluminum impeller, it delivers extreme airflow capacity with superior static pressure performance. Its rugged design and advanced control interfaces make it ideal for demanding environments requiring precise airflow management.
High-Pressure Industrial Performance
Generates up to 7,626 m³/h (4,488 CFM) airflow at 587 Pa static pressure – optimized for ducted systems and high-resistance applications with a robust 8-blade aluminum impeller.
Smart Control Integration
Supports multiple interfaces: 0-10VDC/PWM speed control, tachometer feedback (5 pulses/rev), and RS485 MODBUS communication for seamless automation and real-time monitoring.
Enhanced Environmental Protection
IP54-rated housing resists dust ingress and water splashes, while Class F insulation ensures reliable operation in high-temperature industrial settings (-25°C to 60°C).
Advanced Safety Architecture
Integrates soft-start protection, thermal overload cutoffs, and dedicated alarm contacts (NC/COM) for predictive maintenance and fault detection.
Industrial Process Cooling: Ovens, furnaces, and heavy machinery heat extraction
HVAC Central Systems: Large-scale ducted ventilation and exhaust networks
Energy Infrastructure: Power plant cooling towers and turbine ventilation
High-Static-Pressure Scenarios: Fume extraction and filtration systems
Q1: Does it support network-based control?
Yes. The integrated RS485 interface (Green/Purple wires) enables MODBUS protocol for centralized building management systems (BMS).
Q2: What distinguishes it from standard centrifugal fans?
Its EC motor technology provides higher efficiency (vs. AC motors), variable-speed precision, and lower energy consumption at partial loads.
Q3: Can the +10VDC output (red wire) power external sensors?
Limited to 1.1mA – suitable for signal pull-up (e.g., tachometer) but not for powering devices. Always use with a series resistor.
Q4: Is it compatible with 60Hz power grids?
Yes. Operates at 50/60Hz across 184–270VAC, supporting global voltage standards.
