Product Overview

The FK3G280-2APL-21 is a high-pressure backward centrifugal fan with a support bracket, engineered by Fanova (Suzhou) Motor Technology. Featuring a lightweight yet durable glass-fiber-reinforced plastic impeller and a BLEC102 brushless EC motor, it excels in demanding industrial ventilation systems requiring robust static pressure and corrosion resistance. Designed for continuous operation (S1 duty) in harsh environments, it offers wide voltage compatibility (184–270V AC) and meets CE, RoHS, and ErP2015 standards.


Key Features

  1. Ultra-High Static Pressure & Efficiency
    Delivers industry-leading 718 Pa max static pressure and 3,290 m³/h airflow at 2,500 RPM. The 6-blade plastic-fiberglass impeller (280mm diameter) ensures lightweight operation and corrosion resistance in aggressive environments.

  2. Industrial-Grade Durability
    Combines a die-cast aluminum housing with IP54 protection for dust/water resistance. Operates reliably from –25°C to 60°C and withstands high humidity (5–90% RH), ideal for chemical or marine settings.

  3. Advanced Control & Monitoring
    Supports 0–10VDC/PWM speed control, RS485/MODBUS communication (via RSA/RSB), and alarm switches (NC/COM) for real-time fault alerts. The +10VDC output powers FG tachometers (5 pulses/revolution).

  4. Comprehensive Protection Suite
    Integrates soft-start, thermal overload (motor/electronics), locked-rotor detection, and reverse-polarity safeguards. Ball bearings ensure 50,000-hour lifespan (L10) under continuous operation.


Applications

  • High-Pressure Ventilation: Ducted exhaust in factories, chemical plants, or wastewater facilities.

  • Corrosive Environments: Fume extraction in labs, plating facilities, or coastal installations.

  • Heavy-Duty HVAC: Air handling units (AHUs) requiring sustained high static pressure.


FAQ

Q1: Is the plastic-fiberglass impeller suitable for chemical exposure?
A1: Yes. The glass-fiber-reinforced propylene resists corrosion from mild acids, alkalis, and solvents—ideal for chemical fume extraction.

Q2: Can the alarm switch (NC/COM) trigger external shutdown systems?
A2: Absolutely. The dry-contact output integrates with PLCs or safety relays to halt equipment during fan faults (e.g., overheating).

Q3: How does RS485/MODBUS enhance control?
A3: Enables centralized speed adjustment, diagnostics, and real-time monitoring via industrial automation networks.
