Product Overview

The FK3G280-48PL-20 is a high-performance DC backward centrifugal fan engineered for demanding industrial cooling and ventilation tasks. Featuring a 280mm plastic-GF reinforced impeller and a robust external rotor BLDC motor (Model BLDC102), it delivers exceptional airflow (up to 3,084 m³/h) and static pressure (777 Pa) at 48VDC. Designed with IP44 protection and wide voltage compatibility (36–57VDC), it operates reliably in harsh environments while prioritizing energy efficiency and smart control integration.


Core Features

  1. Industrial-Grade Airflow Power
    Combines a large 280mm impeller with a 395W BLDC motor to move massive air volumes (3,084 m³/h) against high resistance—ideal for cooling heavy machinery or confined spaces.

  2. Built for Tough Environments
    IP44-rated against dust/water ingress and operates across extreme temperatures (-25°C to 60°C). Reinforced with ball bearings and shock-resistant materials for sustained reliability.

  3. Smart Control & Safety
    Supports 0–10VDC/PWM speed modulation and outputs real-time RPM signals (FG tachometer). Integrates multi-layer protection: soft-start, reverse polarity lockout, and thermal overload cutoffs.

  4. Plug-and-Play Flexibility
    Mounts in any orientation with universal brackets. Standard wiring (0–10V/PWM + FG) simplifies integration, while custom cable lengths/communication protocols are optional.


Applications

  • Industrial Equipment: Cooling for CNC machines, laser cutters, power cabinets.

  • HVAC Systems: High-pressure ventilation in factories or warehouses.

  • Energy/EV Infrastructure: Thermal management in battery packs or converters.

  • Data Centers: Auxiliary airflow boosting in server racks.


FAQ

Q: Can it run continuously?
A: Yes, rated for 50,000 hours (L10) at 40°C—suited for 24/7 S1 duty cycles.

Q: Is reverse wiring protected?
A: Yes, reverse polarity protection prevents damage if +/- terminals are misconnected.

Q: Why avoid touching the impeller during startup?
A: Its soft-start design delays rotation; accidental contact may cause injury once spinning.
