Product Overview

The FB3G355-2APK-60 is a corrosion-resistant centrifugal fan engineered for aggressive environments requiring high static pressure. Featuring a unique glass-fiber-reinforced plastic impeller and BLEC102 EC motor, it delivers 5,000 m³/h airflow at 1,000 Pa force. With IP54 protection, MODBUS compatibility, and 230V single-phase operation, it excels in chemical, marine, or high-humidity applications where metal components would degrade.

Key Features

  1. Chemical-Resistant Construction
    Glass-fiber-reinforced polypropylene impeller withstands corrosive fumes, moisture, and salt spray—ideal for wastewater treatment, chemical processing, or coastal installations.

  2. High-Pressure Performance
    Generates exceptional 1,000 Pa static pressure at 2,100 RPM (±5%), enabling airflow through dense filters or long duct runs in compact systems.

  3. Smart Industrial Control
    Supports 0–10V/PWM speed modulation and RS485/MODBUS protocol. Includes +10VDC output for sensors and FG tachometer (5 pulses/rev) for system feedback.

  4. Integrated Safety Monitoring
    Alarm contacts (NC/COM) trigger during faults (overheat, lock-rotor). Protections include reverse polarity blocking and wide voltage tolerance (184–270V AC).

Applications

  • Chemical exhaust: Fume scrubbers, laboratory ventilation.

  • Marine/offshore: Engine room cooling, dehumidification systems.

  • Food processing: Corrosive vapor removal, washdown areas.

  • Industrial dehumidifiers: High-pressure drying systems.

FAQ

Q: Plastic vs. aluminum impeller durability?
A: Superior corrosion resistance but lower max temperature (60°C vs. 80°C for aluminum). Avoid impacts exceeding 50J.

Q: Noise level at full load?
A: 87 dB(A) ±5%—recommend ducted installation or acoustic enclosures.

Q: Can MODBUS replace analog control?
A: Yes. Use RSA/RSB pins for digital speed commands—contact support for MODBUS registers.

Q: Weight specifications?
A: 3,600g (fan)/400g (inlet)—lighter than equivalent metal impellers.
