Product Description
The Siemens G4E280‑BC23‑05 is a high-performance industrial axial fan motor unit designed for ventilation, cooling, and air-handling applications.
It belongs to Siemens’ G4E series of external rotor motors with integrated fans, offering efficient airflow and reliable operation.
Moreover, its compact external rotor design directly mounts the impeller to the motor hub, providing low-noise operation and enhanced cooling efficiency.
Therefore, this fan is ideal for industrial environments requiring consistent airflow and robust performance.
Although discontinued by Siemens, the unit has been fully tested and meets industrial standards for HVAC and machinery cooling applications.
In addition, flange mounting allows easy integration into duct systems, electrical enclosures, or industrial equipment housings.
