The 8315100472 from EBM-Papst is a compact axial fan in the AxiForce40 series, designed for high-performance cooling in a small 40 × 40 × 28 mm format. It is powered by a 12 V DC motor with electronic speed control, offering an impressive static pressure of 305 Pa at 12,000 rpm. Thanks to its integrated locked-rotor protection with automatic restart, it is built for reliable operation in demanding applications.
The fan is ideal for dense electronics, industrial control equipment, and other applications where powerful airflow is required in a confined space. Its optional mounting position makes it easy to integrate into most designs.
