Product Overview

The FK3G400-2AAL-30 is an industrial-grade centrifugal fan engineered for extreme static pressure demands in harsh environments. Featuring an 8-blade aluminum impeller (400mm) driven by a robust BLEC137 EC motor, it delivers 6,260 m³/h (3,684 CFM) airflow at 675 Pa (2.7 in.wg)—the highest pressure in its class. With IP54 protection, Class F insulation, and a vibration-dampened bracket, it withstands continuous operation in high-temperature industrial settings.


Key Features

  1. Heavy-Duty Pressure Performance
    Generates 675 Pa static pressure—ideal for overcoming resistance in dense filtration, long duct runs, or compact heat exchangers. The die-cast aluminum impeller ensures thermal stability at 1700 RPM.

  2. Industrial Resilience
    Class F insulation handles 115°C internal temperatures, while the IP54-rated housing protects against dust/moisture ingress in foundries, chemical plants, or outdoor installations.

  3. Vibration-Optimized Bracket
    Integrated mounting bracket with rubber isolators reduces operational vibrations by 40% (vs. bolt-on solutions), extending equipment lifespan in sensitive machinery.


Typical Applications

  • Industrial Oven Exhausts: High-temperature fume extraction (up to 60°C ambient).

  • HVAC Booster Systems: Overcoming pressure drops in large commercial complexes.

  • Dust Collection Units: Handling abrasive particulates in wood/metal processing.

  • Generator Cooling: Forced-air cooling in backup power systems.


FAQ

Q1: Can the bracket be wall-mounted?
A1: Yes. The universal bracket supports wall, ceiling, or equipment-mounting with 360° adjustability.

Q2: Why is Class F insulation critical?
A2: It allows 25°C higher operating temps than Class B—essential for fail-safe performance near heat sources like furnaces.

Q3: How does it maintain efficiency at partial loads?
A3: EC motor technology enables 30–100% speed modulation via 0–10V/PWM with <5% efficiency loss.
