  • Industrial-grade cooling from genuine Ebmpapst engineering
  • 105 W power delivers up to 35000 m³/h airflow
  • Double ball bearing ensures long-life operation
  • Wide 36–57 VDC range suits 48 V systems
  • Runs reliably from -25 °C to 60 °C

Industrial-grade 48 VDC centrifugal fan

The Fans D1G133-AB39-52Bearing is a new, original German EBM centrifugal fan rated for 48 VDC nominal input with a 36 to 57 VDC operating range. It targets integrators and maintenance teams who need a high-power air mover for industrial enclosures, inverter cooling or telecommunications cabinets where 48 VDC infrastructure is standard.

Double ball bearing and steel construction

A double ball bearing supports the external rotor motor for long service life in continuous duty. The sturdy steel plate housing provides mechanical rigidity and protects the impeller in demanding rack or chassis mounting scenarios. Speed is fully controllable via analog or serial interface, allowing simple integration into open-loop or closed-loop thermal management systems.

105 W draw at 1780 rpm

The fan draws 2.8 A and consumes 105 W at its rated 1780 rpm, delivering airflow up to 35000 m³/h. It is specified for ambient temperatures from -25 °C to 60 °C, making it suitable for harsh environments. The compact external rotor design ensures efficient motor cooling while maintaining high static pressure performance.

Questions about this item

What does the 48 VDC input with a 36–57 V range mean for speed control headroom?

The fan runs at nominal 48 VDC and accepts 36–57 VDC, so speed can be scaled across that full window via analog or serial control.

What mounting pattern and housing does the D1G133-AB39-52 need?

It is a backward-curved centrifugal impeller designed as a free-wheeling fan without a scroll housing, so it mounts directly to the equipment panel.

How is the fan wired for 100 % speed control and what step is often missed?

Connect the 48 VDC supply drawing 2.8 A, then apply the analog or serial control signal; the common miss is powering the motor without the control reference.
