Product Overview

The FB3G400-2APK-60 is a high-capacity centrifugal fan engineered for industrial ventilation demanding extreme airflow and static pressure. Powered by a single-phase 230V AC EC motor (BLEC102), it delivers 6,350 m³/h airflow at 950 Pa static pressure—ideal for large-scale exhaust systems. Its IP54-rated construction integrates smart monitoring via RS485 (MODBUS) and alarm contacts for critical environment applications.


Key Features

  1. Industrial-Grade Airflow Capacity

    • 400mm glass-fiber-reinforced impeller generates massive 6,350 m³/h airflow for warehouses, factories, or smokestack exhaust systems.

  2. Smart Monitoring & Alerts

    • RS485 (MODBUS) enables real-time control via PLCs. Dedicated alarm contacts (NC/COM) trigger warnings for thermal/fault events.

  3. Single-Phase AC Simplicity

    • Operates on standard 230V AC (184–270V range), eliminating complex power conversions while supporting soft-start protection.


Applications

  • Industrial Exhaust: Foundries, chemical plants, welding fume extraction.

  • Large Commercial HVAC: Shopping malls, airport ventilation, data center cooling.

  • Energy Recovery Systems: High-volume ERUs, heat reclaim for industrial processes.


FAQ

Q1: Can this fan replace three-phase units in existing systems?
A: Yes—its single-phase 230V AC design simplifies retrofits without sacrificing performance vs. three-phase alternatives.

Q2: How are alarm contacts (NC/COM) utilized?
A: Connect to PLCs or warning lights; contacts open during faults (overheat, lock-rotor) for immediate intervention.

Q3: Does the plastic impeller handle high temperatures?
A: Glass-fiber reinforcement ensures stability up to 85°C—avoid direct exposure to flames/chemicals.

Q4: Is MODBUS control compatible with legacy systems?
A: Yes—use RSA (A+)/RSB (B-) wires for seamless integration with industrial automation protocols.
