Product Overview

The FK3G133-2APL-50 EC Centrifugal Fan by Fanova Motor Technology combines compact design with high-efficiency ventilation. Featuring a 133mm fiberglass-reinforced impeller and integrated mounting bracket, it delivers 219 m³/h airflow at 228 Pa static pressure. Powered by a 230V AC EC motor (BLEC53), it operates reliably across voltage fluctuations (184–270V AC) with PWM/0–10V speed control. Ideal for space-constrained applications, its IP44-rated housing resists dust and moisture while the lightweight design (650g total) enables flexible installation.


Core Features

  1. Ultra-Efficient Miniature Powerhouse
    Consumes only 18W (±10%)—70% less energy than standard AC fans—while maintaining 3,200 RPM for critical cooling. Self-adjusts to unstable grids (184–270V AC).

  2. Low-Noise Precision Engineering
    Operates at 58.9 dB(A)—quieter than typical office background noise (60 dB). Ideal for medical devices or quiet workspaces.

  3. Bracket-Integrated Flexibility
    Pre-installed mounting bracket simplifies installation in tight spaces:
    – Tool-free attachment to panels or enclosures
    – 360° adjustable airflow direction
    – Vibration-damped design

  4. Smart Control Ready
    Built-in +10V output powers external sensors. FG tachometer signal (2 pulses/rev) enables real-time RPM monitoring for predictive maintenance.


Applications

  1. Compact Electronics Cooling
    Prevents overheating in 1U server racks, telecom cabinets, or IoT gateways. 133mm size fits space-limited enclosures while 228 Pa pressure overcomes filter resistance.

  2. Medical & Diagnostic Equipment
    Ventilates portable ultrasound devices, blood analyzers, or dental tools. Low noise ensures patient comfort during procedures.

  3. Retail & Hospitality Systems
    Covers POS terminals, espresso machines, or hotel HVAC controls. IP44 rating withstands occasional liquid splashes.

  4. 3D Printing & Robotics
    Actively cools printer heads, stepper motors, or control boards. PWM control syncs with temperature spikes during continuous operation.


FAQ

Q1: Can it run on 110V household power?

No. Requires 230V AC. Use a step-up transformer for 110V systems.

Q2: How to further reduce noise below 55 dB(A)?

Set PWM to cap speed at 2,500 RPM. Noise drops to 52 dB(A) with minimal airflow loss.

Q3: Is the bracket rust-proof?

Yes. Aluminum construction with black electrophoretic coating resists humidity.

Q4: Can I daisy-chain multiple fans to one controller?

Yes. Share PWM control wires across units for synchronized speed adjustment.
