Product Overview

The FK3G355-2APK-60 is a high-pressure centrifugal fan engineered for industrial systems requiring robust airflow against significant resistance. Its backward-curved blade design and composite construction deliver exceptional static pressure performance (up to 1000 Pa) while enabling flexible integration into HVAC, filtration, and process cooling applications.


Core Features

  1. Engineered for High-Pressure Demands
    Optimized for restricted airflow environments (e.g., ducted systems, HEPA filters), generating 1000 Pa static pressure to overcome system resistance efficiently.

  2. Composite Impeller for Corrosion Resistance
    Features a glass-fiber-reinforced propylene impeller (355mm) – lighter than metal alternatives and resistant to humidity/chemical exposure, ideal for harsh industrial settings.

  3. Vibration-Optimized Bracket System
    Integrated mounting bracket reduces operational vibrations by >80%, critical for noise-sensitive installations while ensuring stability in any orientation.

  4. Smart Control Ecosystem
    Supports 0–10VDC/PWM inputs, tachometer output (FG), and RS485 Modbus communication (via RSA/RSB wires) for seamless integration into automated building management or IoT platforms.


Applications

  • Industrial Ventilation: Ducted exhaust systems, fume extraction

  • High-Resistance Cooling: Condensers, heat exchangers, enclosed machinery

  • Filtration Systems: HEPA/ULPA filter bypass, cleanroom pressure control

  • Process Air Handling: Manufacturing drying, pneumatic conveying


FAQ

Q: Why choose composite impellers over metal?
A: They offer 40% weight reduction (reducing motor load), resist corrosion in humid environments, and dampen noise at high RPMs – critical for food processing or chemical plants.

Q: How is noise managed at 87 dB(A)?
A: Use variable-speed control to reduce RPM during partial loads. For noise-critical sites (e.g., labs), pair with duct silencers or acoustic enclosures.

Q: Can this fan operate in explosive environments?
A: No – it lacks ATEX certification. For hazardous areas, inquire about our intrinsically safe models.

Q: Is the RS485 protocol customizable?
A: Yes. While Modbus RTU is standard, we support BACnet, CANopen, or custom protocols – contact technical support for firmware options.
