The REF100-11/14 from EBM-Papst is a compact DC centrifugal fan in a FlatPak format with dimensions of 104×25 mm. It is designed for centrifugal operation with axial inlet and radial outlet, and is powered by a 24 V brushless DC motor. Thanks to its flat format and low weight of 165 g, it is ideally suited for applications where space is limited.
The REF100-11/14 is suitable for cooling and ventilation in electronic cabinets, medical equipment, and industrial applications with controlled environments. Optional mounting positions provide great flexibility for integration into existing systems.

| Motor frame | The fans are supplied without a housing and are mounted with the shaft in any position. The depth is 25.0 mm and the diameter is 104.0 mm. The unit weighs 0.165 kg and is intended for use in protected environments with controlled temperature and humidity. |
| Casing | plastic |
| Impeller | The fan impeller is made of plastic and is designed for centrifugal operation (blower) without a casing and without an inlet nozzle. Air flows in axially and out radially. The fan impeller achieves a maximum free air flow of 86 m³/h and a maximum static pressure of 340 Pa at 5,200 rpm. |
| Bearing type | ball bearing |
| Motor protection | automatic restart at locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a brushless DC motor designed for 24 V nominal voltage with a voltage range of 16–30 V. Power consumption at free airflow is 7.4 W and current consumption is 313 mA. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The estimated service life is 80,000 hours (L10) at 40 °C. |
