The W3G250-EC28-11 from EBM-Papst is a robust axial fan with a wall ring for DC current, designed for demanding industrial ventilation applications. The fan delivers an impressive airflow of up to 1,785 m³/h and is powered by a brushless DC motor, type M3G074-BA, with a nominal voltage of 26 V DC. With an ingress protection rating of IP6K9K for the electronics and IP24KM for the motor, it can withstand harsh environments without issue.
The fan is excellently suited for industrial units, cooling systems, and ventilation systems where high performance, long service life, and flexible mounting are required.
