W3G300-BV24-81 ebmpapst 26V 3160RPM 205W 300mm Axial Fan

Description

The ebmpapst W3G300-BV24-81 is a high-performance 26 V industrial axial fan with a 300 mm diameter, meticulously engineered for critical thermal management in transport and railway environments. This unit integrates a high-torque M3G084-BF motor with a motor size of 84, optimized for a 205.0 W power envelope to drive its specialized 7-blade HyBlade impeller to a peak velocity of 3160 RPM. Designed for continuous S1 operation under extreme conditions, it features advanced electronics including temperature derating, power limiting, and a 58 V load dump protection. The mechanical foundation consists of a precision-balanced, sealed dual ball bearing system and a glass-fiber reinforced PA plastic housing, providing 70,000 hours of reliable service. Featuring an intelligent 4-wire interface with INVLIN (inverse linear) control and a dual IP24/IP6K9K protection rating, this fan is a critical component for vehicle climate control and railway technology where maximum reliability and safety extra-low voltage (SELV) operation are mandatory.
