The FB3G310-2AAS-30 is a high-capacity backward centrifugal EC fan for industrial air handling, delivering 4482 m³/h airflow and 933 Pa static pressure. Powered by a 230VAC external rotor motor (BLEC137), it operates at 2600 RPM with IP54 protection and Class F insulation. Compliant with CE, RoHS, and ErP standards, it features integrated Modbus communication and is designed for continuous duty (S1) in harsh environments up to 60°C.
Global Voltage Compatibility
Accepts 184–270V AC at 50/60Hz, eliminating the need for external converters in international installations.
Advanced Control Ecosystem
Supports 0-10V/PWM speed control, outputs FG tach signals (5 pulses/rev), and enables RS485 Modbus (via RSA/RSB) for IoT-ready system integration.
High-Efficiency Aluminum Impeller
An 8-blade die-cast aluminum design minimizes turbulence while achieving 84 dB(A) noise at full load—ideal for high-static-pressure applications.
Enhanced Electrical Safety
Exceeds industrial standards with 1800VAC dielectric resistance and ≤3.5mA leakage current, backed by reverse-polarity/locked-rotor protection.
Large-Scale Ventilation: Factory air scrubbers, industrial ovens, and drying systems requiring >900 Pa static pressure.
Smart Building Management: Integration with BMS (Building Management Systems) via Modbus for real-time airflow monitoring.
Energy Recovery Systems: Heat exchangers and HVAC units where AC power compatibility reduces conversion losses.
Q1: Can the +10VDC output power external sensors?
A: No. It supplies max 1.1mA—only for signal pull-up (e.g., FG tach). Use external power for sensors.
Q2: How to wire the alarm contacts (Orange/Gray)?
A: Connect to a PLC input. The contacts close if the fan faults (e.g., overheating/lock). See Fig. 8.
Q3: Is Modbus protocol customizable?
A: Yes. Default is MODBUS-RTU, but protocols like BACnet can be configured—contact tech support .
Q4: Why choose this over DC fans?
A: Direct AC operation avoids DC conversion losses, and 230VAC enables longer cable runs without voltage drop.
Q5: What maintenance do ball bearings require?
A: Sealed bearings last 50,000 hours (L10) at ≤80°C. No relubrication—replace if abnormal noise occurs.
