Product Overview

The FB3G355-2AAS-30 is a high-power 355mm EC centrifugal fan engineered for large-scale ventilation. Operating at 230VAC, it delivers a colossal 5400m³/h airflow and 750Pa static pressure—ideal for overcoming resistance in ducts or dense systems. Its brushless motor (BLEC137) integrates smart controls and industrial certifications (IP54, Class F insulation).

Key Features

  1. Industrial-Grade Airflow Force
    Generates turbine-like pressure (750Pa) to move air through long ducts, filters, or packed machinery—equivalent to commercial HVAC blowers.

  2. Smart Connectivity Hub
    Features RS485/MODBUS communication for automation, plus a built-in +10VDC output to power external sensors or controllers without extra wiring.

  3. Heavy-Duty Construction
    Aluminum impeller and housing withstand vibration, moisture, and dust (IP54-rated). Class F insulation ensures reliability in 60°C environments.

  4. Proactive Safety System
    Includes alarm contacts (NC/COM) for failure alerts, soft-start protection, and leakage current control (<3.5mA)—critical for 750W systems.

Applications

  • Factory Ventilation: Fume extraction in welding/painting bays.

  • Commercial HVAC: Air handling units (AHUs) or rooftop units.

  • Industrial Ovens: High-temp exhaust for baking/drying processes.

  • Power Electronics: Cooling large inverters or transformer cabinets.

  • Data Centers: Thermal management in server farm ductwork.

FAQ

Q1: Why does it need 230VAC? Can it run on lower voltage?
A: No. Designed for industrial grids (184–270VAC). Lower voltages trigger undervoltage shutdown.

Q2: How is the +10VDC output used?
A: It powers tachometers (FG) or PWM controllers—eliminating external power supplies. Max load: 1.1mA.

Q3: What if the alarm contacts (orange/grey) close?
A: Signals motor failure (e.g., overheating). Wire them to PLCs or warning lights for instant alerts.

Q4: How do I enable MODBUS control?
A: Connect green (RSA) and purple (RSB) wires to RS485 devices. Protocol details: contact Fanova Tech.
