The 3856 from EBM-Papst is a compact axial fan with a wall ring, designed for reliable ventilation in professional applications. The unit features a square metal housing measuring 92 × 92 × 38 mm and is powered by a 230 V AC motor at 50/60 Hz. Thanks to ball bearings and an expected lifespan of 60,000 hours at 40 °C, it offers long and reliable operation.
The fan is ideal for electronics cabinets, medical equipment, and industrial devices where quiet and efficient cooling is required. The optional mounting position and the 310 mm long connection cable make installation easy and flexible.
