The 6224NU from EBM-Papst is a robust DC axial fan with a wall ring, designed for axial airflow in demanding environments. With a metal housing and dimensions of 172×172×51 mm, it fits into a wide range of industrial installations. Its impressive IP68 protection class makes it suitable even for applications where the fan may be subjected to complete submersion in water.
The fan is an excellent choice for applications in marine engineering, process industry, cooling systems, and other environments where high air performance is combined with requirements for water resistance. The flexible voltage range of 12–28 V DC makes it easy to integrate into existing systems.

|---|---|
| Airflow at 0 Pa | 390 m³/h |
| Speed | 3400 rpm |
| Power | 17 W |
| Voltage | 24V DC VAC |
| Motor frame | The casing is made of metal and has a diameter of 172 mm and a depth of 51 mm. ISO 4762 M4 fastening screws are used for mounting. The mounting position for the shaft is optional, and when mounting across both flanges, a maximum torque of 600 Ncm per corner is permitted. |
| Casing | metal, round |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. Air is discharged over the struts. At a nominal speed of 3400 rpm, the fan impeller provides a maximum free airflow of 390 m³/h and a maximum static pressure of 180 Pa. The optimal operating point is 285 m³/h at 58 Pa. |
| Bearing type | ball bearing |
| IP class | IP68 |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 12–28 V. With free airflow and nominal voltage, the motor consumes 17 W with a current consumption of 710 mA. The motor has built-in locked rotor protection with automatic restart and reverse polarity protection via diode. The ingress protection rating is IP68, which means the fan can withstand complete submersion in water. |
