The 8218JH3 from EBM-Papst is a compact and powerful DC axial fan with a wall ring, designed for demanding cooling applications. Measuring 80 × 80 × 38 mm, the fan operates with S-Force technology for maximum airflow in a small form factor. With a nominal voltage range of 20–58 V DC, it is widely suitable for modern systems.
Thanks to its high airflow and compact size, the 8218JH3 is an excellent choice for industrial electronics cooling, server cabinets, and other equipment where efficient air circulation is crucial in confined spaces.

|---|---|
| Airflow at 0 Pa | 190 m³/h |
| Speed | 12,000 rpm |
| Power | 25W |
| Voltage | 48 V DC VAC |
| Motor frame | The housing is square with dimensions 80 × 80 × 38 mm and made of plastic. Mounting is done with M4 screws (ISO 4762) without washers and without additional support structures. The maximum tightening torque varies depending on the mounting corner: 50 Ncm at the cable outlet corner and 110 Ncm at the other corners. The mounting position for the shaft is optional. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. Airflow is directed over the struts (air outlet over struts). At 12,000 rpm and free airflow, a maximum airflow of 190 m³/h and a maximum static pressure of 490 Pa are delivered. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with speed control and a nominal voltage of 48 V DC. The voltage range extends from 20 V to 58 V. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. The rated power is 25 W at free airflow. |
