Fans W3G300-BV25-33Motor case fan 26V 380W 330mm 3940rpm

SKU CH-WPCY-23CJK MPN W3G300-BV25-33Motor

An axial case fan delivering 380 W at 26 V with a 330 mm impeller spinning at 3940 rpm

  • High airflow up to 35000 m³/h for effective cooling
  • 380 W motor delivers strong performance at 26 V
  • 330 mm blade diameter fits large enclosures
  • 3940 rpm speed enables rapid air exchange
  • 100 % speed control via analog or serial interface

Industrial cooling scope

The ebmpapst W3G300-BV25-33Motor is a 330 mm axial fan built for equipment that moves large volumes of air through heat exchangers. It runs on 26 V DC, draws 14.6 A and delivers 380 W of motor power at 3940 rpm. The GreenTech EC design adds full speed control via analog or serial interface.

Upgrade justification

This unit replaces smaller or fixed-speed axial fans when airflow must reach 35000 m3/h and the installation depth is limited. The jump is worth it when the application demands 100 % variable speed, low acoustic signature and the reliability of an external-rotor motor with forced electronic cooling.

Build integration

The compact steel-plate housing fits tight enclosures and connects through a plug-and-play interface that includes matched open-loop control components. It frees the designer from sourcing separate motor, fan and controller modules, while the 26 V supply requirement and 14.6 A current draw define the power-budget envelope for the surrounding system.

Highlights

  • High airflow up to 35000 m³/h for effective cooling
  • 380 W motor delivers strong performance at 26 V
  • 330 mm blade diameter fits large enclosures
  • 3940 rpm speed enables rapid air exchange

Questions about this item

What diameter opening does the 330mm fan need for mounting?

The axial fan requires a 330mm diameter opening for the blade sweep and a flat surface to bolt the steel plate housing.

How is the 26V EC motor wired for speed control?

Connect the 26V supply and use the analog or serial interface for 100% speed control; the plug-and-play design matches the motor and controller.

When should the steel plate housing or bearings be inspected?

Inspect the sturdy steel plate and external rotor motor bearings during scheduled maintenance intervals for the 380W centrifugal fan.
