SKU CH-B2WE-AE4H6 MPN G1G133-DE03-S01Motor

A 133 mm centrifugal case fan delivering 45 W at 48 V and 2000 RPM for industrial and specialised cooling applications

  • 133 mm blade diameter fits tight enclosures
  • 48 V 45 W motor delivers strong airflow
  • 2000 RPM speed ensures rapid heat removal
  • Centrifugal design creates focused static pressure
  • Custom processing available for specialised applications

48 V Centrifugal Fan for Industrial Cooling

This 133 mm centrifugal fan runs on 48 V DC and draws 1.1 A at 45 W. It spins at 2000 RPM to move air through dense heatsinks or restricted ducts. The unit suits medical devices, rail vehicles, EV systems and industrial equipment that need focused airflow.

Thermals and Acoustics at 2000 RPM

At full speed the motor delivers 45 W of cooling power while operating from a 48 V supply. Centrifugal geometry builds static pressure so heat is pushed through tight channels without stalling. Noise level varies with duct design and mounting rigidity.

Build Integration and Mounting Constraints

The 133 mm blade diameter fits standard centrifugal cut-outs used in drive cooling and hotel HVAC modules. Wiring requires a 48 V DC source capable of 1.1 A continuous current. No PWM or tachometer signals are documented, so speed control must be handled externally.

Questions about this item

How do I wire the 48 V supply to the G1G133-DE03-S01Motor and which step is most often missed?

Connect the fan's two leads to a 48 V DC source rated for at least 1.1 A; the step most often missed is verifying polarity before powering on, because reversing the leads will prevent the centrifugal motor from starting.

What maintenance will this 133 mm centrifugal fan need over time?

Plan to clean dust from the blades and housing every few months and listen for bearing noise; if the 45 W motor develops vibration or speed drops below 2000 RPM, replace the entire unit as bearings are not user-serviceable.

What is the first limit reached when this fan runs continuously at 2000 RPM?

The motor's 45 W power rating and 1.1 A current draw set the thermal limit; sustained operation at full speed will hit the winding temperature ceiling before any airflow restriction appears.
