W3G910-LV12-03/F01 ebmpapst 400V 910mm EC Axial Fan

Description

The ebmpapst W3G910-LV12-03/F01 is a high-capacity industrial EC Axial Fan powered by the high-torque M3G150-NA motor, featuring a 910 mm impeller designed for massive air movement in large-scale cooling infrastructures. Operating on a 3-phase 400 VAC supply, this unit is rated at a nominal speed of 1070 RPM with a power consumption of 3250 W and a current draw of 5.0 A. The fan is mounted within a robust 1070 x 1070 x 321 mm square wall plate assembly, providing both structural stability and optimized airflow characteristics for heavy-duty installations. Built with a 5-blade PP plastic impeller and weighing 54.6 kg, the fan delivers a maximum back pressure of 300 Pa (1.2 in. wg) while maintaining an IP55 protection rating. It represents a state-of-the-art thermal solution for data center chillers and industrial HVAC systems, combining ebmpapst’s signature EC efficiency with advanced features like soft start, motor current limitation, and an integrated PI controller.
