The ebmpapst 4650X is a compact axial cooling fan for industrial automation and electronic equipment. Its space-saving format fits control cabinets, embedded electronics and automation assemblies that need a direct airflow path for continuous heat removal.
Key selection data includes a 230 V supply, airflow up to 170 m³/h, and maximum pressure of 90 Pa. The axial flow path provides efficient cooling, while pressure performance helps move air through guards, filters and restricted passages. The datasheet identifies sleeve-bearing motor support for durable motor support. 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.
This industrial fan suits OEMs, integrators and maintenance teams. Verify the duty point, connector, mounting and ambient limits against the exact datasheet. Correct installation and a clean airflow path support reliable long-term operation.
