A 133 mm centrifugal case fan running at 2000 rpm from a 48 V, 45 W, 1.1 A motor

  • High airflow up to 35000 m³/h for demanding cooling
  • 48 V 45 W motor delivers strong performance at 2000 rpm
  • 133 mm centrifugal impeller with external rotor for compact design
  • 100 % speed control via analog or serial interface
  • Genuine ebm-papst build with sturdy steel housing

Industrial centrifugal blower

The Fans G1G133-DE03-S01Motor is a centrifugal blower built by ebmpapst for industrial and commercial equipment. It runs on 48 V DC, draws 1.1 A and is rated at 45 W. The impeller diameter is 133 mm and the motor spins at 2000 rpm.

Suited for 48 V DC systems only

This blower fits machines and enclosures that supply 48 V DC directly. It is not suitable for builds that only provide standard PC fan headers or consumer power supplies without a matching 48 V source. Installers who cannot deliver 48 V DC at 1.1 A should choose a different fan.

48 V DC input voltage

The single specification that decides fit is the 48 V DC operating voltage. The unit requires a 48 V supply capable of 1.1 A; without that exact rail the fan will not run. Verify your system provides 48 V DC before ordering.

Questions about this item

What distinguishes the 45W 48V version from other ebm-papst centrifugal models?

This model delivers 45W motor power at 48V with 1.1A current, a 133mm blade diameter and 2000 rpm speed, giving up to 35000 m³/h airflow in a compact external-rotor design.

How does the 35000 m³/h airflow figure translate to actual case cooling performance?

The 35000 m³/h maximum airflow moves large air volumes through restrictive chassis layouts, while the 2000 rpm centrifugal impeller maintains static pressure for dense fin stacks or radiator mounts.

What control interface does the fan use and what speed range does it support?

It supports 100% speed control via analog or serial interface, allowing full 0-2000 rpm adjustment for precise thermal management.
