The 612NHU-181 from EBM-Papst is a compact DC tubeaxial fan measuring 60x60x25 mm with an operating voltage of 12 V DC. The fan is built for demanding environments and has an IP68 rating, which means that the electronics and windings are completely encapsulated to withstand permanent submersion in water. This makes it a reliable choice when ordinary fans are not sufficient.
The fan is excellent for applications where moisture, dust, or corrosive environments place high demands on the component – for example, in marine technology, outdoor installations, and industrial equipment.
- IP68 protection class – withstands permanent submersion

|---|---|
| Airflow at 0 Pa | 42.8 m³/h |
| Speed | 5600 rpm |
| Power | 1.8 W |
| Voltage | 12 V DC VAC |
| Motor frame | The casing is made of glass fiber reinforced PBT composite and measures 60x60x25 mm. The fan has UL approval and is designed for use in demanding environments thanks to its IP68 rating. Connection is made via 310 mm long wires of type AWG 22, TR 64, stripped and tinned. |
| Casing | fiberglass-reinforced PBT composite, square 60x60x25 mm |
| Impeller | The fan impeller is made of glass fiber reinforced PA composite for high strength and corrosion resistance. It rotates clockwise when viewed from the rotor side and provides an airflow of 25.3 CFM (approx. 42.8 m³/h). The air is discharged over the struts. The sound pressure level is 37 dB(A). |
| Bearing type | ball bearing |
| IP class | IP68 |
| Motor protection | reverse polarity and interlocking protection |
| Rotation direction | clockwise, viewed from the rotor side |
| Motor type | The motor is a DC motor with reverse polarity and lock protection. It has an IP68 enclosure rating, which means the electronics and windings are fully encapsulated to withstand permanent submersion in water. The operating voltage is nominally 12 V DC with a voltage range of 8–15 V DC. Power consumption is 1.8 W at a nominal speed of 5600 rpm. |
