The ebmpapst 3412N/39H is a compact DC axial cooling fan intended for server and IT equipment. It integrates into equipment enclosures and automation modules where localized heat loads require stable air exchange in limited space.
Key selection data includes a 12 V supply, airflow up to 91 m³/h, and maximum pressure of 50 Pa. The axial flow path provides efficient cooling, while pressure performance helps move air through guards, filters and restricted passages. Its integrated frame, impeller and motor support stable ventilation. Clear inlet and outlet spacing helps control turbulence and system noise. Matching the electrical supply and duty point supports energy-efficient, reliable operation and long service life.
The 3412N/39H suits equipment builders and repair teams seeking a compact industrial fan. Confirm system resistance, wiring, mounting and ambient limits. Applied correctly, it delivers dependable service as a long-life cooling fan.
