The 8312/12HL-118 from EBM-Papst is a compact DC tubeaxial fan, designed for reliable and quiet cooling in demanding applications. The fan delivers up to 67 m³/h of airflow at 4,200 rpm and is powered by 12 V DC. With a rounded PBTP housing and ball bearings, it is built for a long and reliable service life.
Thanks to the built-in TTL-compatible speed sensor, the fan is ideally suited for systems where continuous speed monitoring is required – for example, in industrial electronics, control systems, and medical equipment. The supply voltage can be varied between 6–15 V DC for easy regulation of airflow and noise level.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 67 m³/h |
| Speed | 4200 rpm |
| Power | 3.9 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan housing is made of PBTP. The unit weighs 0.170 kg and is approved according to UL, CSA, and VDE. A TTL logic square wave sensor for speed monitoring is included, providing 2 pulses per revolution. |
| Casing | PBTP, round |
| Impeller | The fan impeller is made of PA 6.6 and is designed for axial flow with a diameter of 80 mm. The airflow and sound level can be regulated by varying the supply voltage within the range of 6–15 V DC. The maximum air volume is 67 m³/h. |
| Bearing type | ball bearing |
| Motor protection | PTC resistor |
| Motor type | The motor is an electronically commutated external rotor motor with DC operation and high efficiency. The drive electronics are fully integrated into the fan hub. Electronic lock protection is integrated into the fan circuit, and a PTC thermistor protects against overload, with a restart after approximately 15 seconds delay. Electronic reverse polarity protection prevents the fan from starting with incorrect polarity. |
