Fans D1G133-AB39-22Motor 48V 105W 133mm 1780 RPM industrial cooling fan
A 48 V centrifugal fan with a 133 mm impeller spinning at 1780 RPM to deliver 105 W of industrial cooling
- 105 W motor power drives strong airflow
- 48 V DC supply suits industrial equipment
- 1780 RPM delivers high-speed cooling
- 133 mm blade diameter fits compact housings
- German ebm-papst build ensures reliable operation
Product identity
This is a 48 V, 105 W centrifugal fan built by ebmpapst for industrial cooling duties. It targets engineers and integrators who need reliable forced-air cooling in medical, rail, drive or hotel infrastructure.
Thermals noise and power
The motor draws 2.8 A at 48 V and spins at 1 780 rpm, delivering up to 35 000 m³/h airflow. External-rotor construction keeps the motor cool, while 100 % speed control via analog or serial interface lets the system tune noise and power to load.
Upgrade context
It replaces failed or undersized centrifugal units in existing 48 V systems where compact, speed-controllable airflow is required. The jump is worth it when the current fan cannot meet airflow targets or lacks the electronic cooling and control integration this model provides.

Questions about this item
How is the 133 mm centrifugal fan mounted and which wiring step is most often missed?
The fan uses an external-rotor motor inside the impeller for a compact footprint; the step installers miss is connecting the 48 V supply to the correct polarity and the 0–10 V or PWM speed-control line so the EC motor can start.
What maintenance will the D1G133-AB39-22Motor need after extended operation?
Periodically clean the backward-curved blades and housing to maintain the 35000 m³/h airflow rating and verify the 2.8 A current draw remains stable; the sealed EC motor bearings are not user-serviceable.
What is the first limit reached when the fan runs continuously at 1780 RPM?
The 105 W motor power rating is the primary thermal limit; sustained operation at 48 V and 2.8 A will hit this ceiling before the 100 % speed-control range or mechanical wear becomes a factor.
