Product Overview

The FB3G250-2AAY-30 is a high-pressure 230V AC centrifugal blower engineered for extreme-resistance industrial applications. Featuring a 250mm aluminum impeller and EC motor technology, it delivers unmatched static pressure performance for systems where airflow must conquer dense filters, long ducts, or confined spaces.


Core Features

  1. Record Static Pressure Output
    Generates 1,077 Pa (4.31 In.wg) – the highest in its class – enabling airflow through heavily restricted industrial systems.

  2. High-RPM Performance
    Operates at 3,000 RPM for aggressive airflow (3,430 m³/h) in demanding cooling/exhaust scenarios.

  3. Thermal Resilience
    Class F insulation withstands higher temperatures than standard Class B motors, ideal for hot industrial environments.

  4. Industrial Control Hub
    Integrates RS485 MODBUS (green/purple wires), 0-10VDC/PWM input (yellow), and +10VDC output (red) for sensor/slave device power.


Applications

  • Extreme Filtration Systems: HEPA-filtered cleanrooms, pharmaceutical manufacturing exhaust, nuclear facility ventilation.

  • Heavy Industrial Processes: Chemical fume scrubbers, welding smoke extraction, foundry dust collection.

  • High-Pressure HVAC: Laboratory exhaust stacks, hospital isolation room ventilation, semiconductor cleanrooms.

  • Power Infrastructure: Transformer cooling, wind turbine nacelle pressurization, mining equipment ventilation.

  • Industrial Vacuum Systems: Large-scale material handling, pneumatic conveying support.


FAQ

  1. Q: Why choose this fan for high-resistance systems?
    A: Its 1,077 Pa static pressure outperforms standard blowers, maintaining airflow in clogged filters or 20m+ duct runs.

  2. Q: What does Class F insulation enable?
    A: Operates at 155°C (vs. 130°C for Class B), extending lifespan in foundries or engine rooms.

  3. Q: Can I monitor it remotely?
    A: Yes – use RS485 MODBUS (green/purple wires) for real-time RPM/fault data in SCADA systems.
