The FB3G280-2APL-20 is a space-optimized EC centrifugal fan for medium-duty industrial airflow systems. Driven by a 230VAC motor (BLEC102), its 280mm composite impeller delivers 3642 m³/h airflow and 891 Pa static pressure at just 500W power. With IP54 protection, Class B insulation, and integrated Modbus communication, it operates continuously (S1) in -25°C to 60°C environments.
Lightweight High-Pressure Design
A 6-blade PP+GF impeller reduces mass by 30% vs. metal alternatives while maintaining 891 Pa pressure for ducted systems up to 15m.
Real-Time Fault Monitoring
Dedicated alarm contacts (Orange/COM-Gray) trigger upon lock-rotor or overheating—connect to PLC for instant system alerts.
Optimized Acoustic Profile
Generates only 80.7 dB(A) at full load—20% quieter than comparable metal impellers—due to aerodynamic blade geometry.
Energy-Smart Operation
Draws 2.2A at 230VAC with soft-start control, minimizing inrush current in battery/UPS-backed installations.
Industrial Process Cooling: Laser cutters, CNC machines requiring 800+ Pa static pressure.
Compact HVAC Units: Rooftop units and air handlers where weight reduction is critical.
Modular Ventilation Systems: Plug-and-play integration with BMS via RS485 Modbus (RSA/RSB).
Q1: How to use the alarm contacts?
A: Wire Orange (NC) and Gray (COM) to a PLC input. Contacts close during faults (e.g., temperature >85°C or motor lock).
Q2: Is plastic impeller suitable for 891 Pa pressure?
A: Yes. Glass-fiber reinforcement ensures stability at 2750 RPM. Avoid abrasive particle ingress.
Q3: Can RPM be controlled via Modbus?
A: Yes. Use RSA (Green) and RSB (Purple) for MODBUS-RTU speed commands—default protocol, others configurable.
Q4: Why choose this over the FB3G310 model?
A: 15% smaller footprint, 38% lower power, and equivalent pressure—ideal where space/power are constrained.
