BG-AUX-OEB012I is a dual-function electric auxiliary unit that integrates an oil-free air brake compressor and a hydraulic steering pump into a single compact assembly. Designed for electric and hybrid commercial vehicles, it delivers reliable compressed air for braking systems while providing hydraulic power for steering operation.

By combining two essential vehicle functions into one unit, BG-AUX-OEB012I eliminates the need for a standalone steering pump, reducing chassis space requirements, system weight, and installation complexity. The integrated architecture helps simplify vehicle packaging and supports more efficient vehicle electrification.

Available in two configurations, the system offers air delivery up to 400 L/min and steering pump displacement up to 14 ml/rev, providing flexible solutions for a wide range of commercial vehicle applications. Its oil-free compressor design ensures clean operation and reduced maintenance requirements, while the IP68-rated enclosure and 3G vibration resistance enable dependable performance in demanding operating environments.
