The FB3G250-2AAY-30 is a high-capacity centrifugal fan designed for industrial-scale ventilation. Featuring a powerful BLEC137 EC motor and 8-blade aluminum impeller, it delivers exceptional 3,430 m³/h (2,019 CFM) airflow at 1,077 Pa static pressure. Operating at 230VAC with Class F insulation, it provides robust performance for demanding applications requiring high airflow volumes and pressure capabilities.
1. Industrial Airflow Capacity
8-blade aluminum impeller generates massive 3,430 m³/h airflow - ideal for large-space ventilation. High-pressure capability (1,077 Pa) overcomes significant system resistance.
2. Premium Motor Technology
BLEC137 EC motor operates at 3,000 RPM with Class F insulation for superior thermal resilience. Delivers 750W output while maintaining energy efficiency versus traditional AC motors.
3. Advanced Control System
Integrated RS485/MODBUS communication enables building automation integration. Includes 0-10VDC/PWM speed control + tachometer output (5 pulses/rev) for precision monitoring.
4. Heavy-Duty Protection
IP54-rated construction withstands dust/moisture ingress. Features alarm contacts (NC/COM) for immediate fault notification and 1800VAC dielectric protection.
Large industrial ventilation systems
Factory air makeup units
High-capacity HVAC central units
Process drying/cooling operations
Concert hall/arena air circulation
Q: What does Class F insulation provide?
A: 25% higher temperature tolerance than Class B - ideal for sustained heavy loads.
Q: Noise level at maximum output?
A: 87 dB(A) - recommend vibration isolation mounts for noise-sensitive installations.
Q: MODBUS implementation details?
A: Standard MODBUS-RTU protocol via RSA/RSB terminals (contact support for custom mapping).
Q: Alarm contact triggering conditions?
A: NC/COM closes during overheat, lock-rotor, or voltage fault events.
