Product Overview

The FK3G250-2AGL-90 is a high-performance backward-curved centrifugal fan engineered by Fanova Motor Technology for demanding industrial airflow applications. Featuring a 250mm galvanized steel impeller and integrated support bracket, it combines rugged construction with exceptional static pressure (605 Pa) and efficient EC motor (BLEC92) technology. Designed for heavy-duty cooling in constrained spaces, its IP44-rated housing and versatile mounting make it ideal for harsh environments.


Core Features

  1. Industrial-Grade Static Pressure Performance
    Delivers 605 Pa (2.42 in.wg) – ideal for overcoming resistance in ducted systems or dense filter arrays – while consuming only 150W at 2,750 RPM.

  2. Integrated Voltage Output & Precision Control
    Features a +10VDC auxiliary output (max 1.1mA) for tachometer (FG) signal support or control integration, alongside PWM/0–10VDC speed input and 4-pulse FG feedback per revolution.

  3. Heavy-Duty Bracket-Mounted Design
    Pre-installed support bracket enables rigid, vibration-free installation in any orientation, paired with corrosion-resistant galvanized steel impeller for longevity.

  4. Universal AC Power & Protections
    Operates on 184–270V AC (50/60Hz) with soft-start, thermal/voltage safeguards, and reverse-polarity protection for failsafe operation.


Applications

  • Industrial Process Cooling: Forcing airflow through ovens, dryers, or combustion systems.

  • Dust Collection Systems: Handling high-resistance ductwork in woodworking or metal processing.

  • HVAC Boosters: Enhancing pressure in commercial ventilation or cleanroom environments.

  • Power Electronics: Cooling high-density inverters, transformers, or UPS cabinets.


FAQ

Q: Can the bracket withstand outdoor vibrations?
A: Yes. The reinforced bracket is designed for industrial environments but avoid direct weather exposure (IP44 = splash-resistant only).

Q: How does the 4-pulse FG signal benefit monitoring?
A: Doubles the resolution of standard 2-pulse outputs, enabling finer RPM tracking for predictive maintenance.

Q: Is the +10VDC output protected from short circuits?
A: No. External current-limiting is required if used as a pull-up source (max 1.1mA).

Q: Can it replace forward-curved fans in existing systems?
A: Backward-curved blades offer higher efficiency at elevated pressures but verify airflow compatibility first.
