Product Overview

The FK3G133-24PL-70 is a compact 24VDC backward centrifugal fan engineered for space-constrained cooling applications where low noise and efficient airflow are critical. With its 133mm impeller and optimized blade design, it delivers focused cooling performance while operating at whisper-quiet sound levels (63 dB), making it ideal for electronics, medical devices, and precision equipment.


Core Features

  1. Ultra-Quiet High-Speed Operation
    Achieves ≤63 dB(A) at 3800 RPM – quieter than typical office environments – via aerodynamically tuned blades and precision balancing (G6.3). Ideal for noise-sensitive settings like labs or audio systems.

  2. Compact Power Efficiency
    24VDC operation (16–28V range) minimizes energy loss in low-voltage systems while providing robust airflow (380 m³/h) and static pressure (343 Pa) for confined spaces.

  3. Reinforced Lightweight Impeller
    Glass-fiber-reinforced plastic blades resist deformation at high RPMs while reducing weight and corrosion risk versus metal alternatives.

  4. Plug-and-Play Control
    Simple 0–10VDC/PWM speed input + FG tachometer output (4 pulses/rev) enables real-time RPM monitoring without complex wiring or protocols.


Applications

  • Electronics Cooling: Server blades, PLC cabinets, IoT gateways

  • Medical Devices: Portable diagnostics, imaging equipment

  • Consumer Tech: High-end AV systems, gaming consoles

  • Transportation: EV charging modules, rail electronics


FAQ

Q: Why choose 24VDC over 12V fans?
A: 24VDC cuts current draw by 50% (vs. 12V), reducing voltage drop in long wire runs and enabling thinner cables – critical for distributed systems.

Q: Is the plastic impeller durable at 3800 RPM?
A: Yes. Glass-fiber reinforcement ensures stability at high speeds, withstanding 85°C continuous air temperatures without warping.

Q: How is noise minimized despite high RPM?
A: Asymmetric blade spacing disrupts harmonic resonance, while backward-curved blades reduce turbulence – lowering tonal peaks by 15% vs. symmetric designs.
