The ebmpapst 6224N is a compact DC axial cooling fan for variable-frequency drives, control cabinets and enclosed electronics. 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 24 V supply, and airflow up to 390 m³/h. The axial flow path provides efficient cooling, while pressure performance should be checked against filter and enclosure resistance. The datasheet identifies ball-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.
6224N Maintains airflow around variable-frequency drives and power electronics to reduce heat buildup inside control enclosures.
6224N Supports continuous air exchange in control cabinets, helping manage localized heat around drives, controllers and power devices.
