The 8315100209 from EBM-Papst is a compact AxiTwin axial fan with a wall ring, designed for demanding cooling and ventilation applications. The fan measures 100×100×90 mm and is powered by an electronically speed-controlled DC motor with a rated voltage of 48 V and a wide voltage range of 36–60 V. Its unique two-stage design with separate PWM and tacho signals provides precision and flexibility in control.
The fan is ideal for dense industrial environments where high airflow is required in a small space, such as server racks, power electronics, and industrial automation.
