The 6448/17U-365 from EBM-Papst is a DC tube axial fan with an electronically commutated external rotor motor, designed for efficient and quiet axial flow in demanding environments. The fan delivers up to 410 m³/h at nominal voltage and is equipped with an alarm signal output via open collector. The integrated operating electronics and the encapsulated stator provide IP54 protection, making it suitable for harsher operating conditions.
Thanks to the aerodynamically optimized impeller and quiet operation, the 6448/17U-365 is well suited for ventilation in control cabinets, industrial equipment, and systems where operational reliability and low noise levels are crucial. The integrated mounting housing simplifies installation.

|---|---|
| Airflow at 0 Pa | 410 m³/h |
| Speed | 3400 rpm |
| Power | 17 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan is equipped with an integrated mounting bracket. Fastening is done with screw DIN 7500C M4x6 (applies only to model 6448). Dimensions and mounting holes are shown in the dimension drawing in the data sheet. |
| Impeller | The fan impeller is aerodynamically optimized to minimize the noise level. It is designed for axial flow and delivers a maximum airflow of 410 m³/h at nominal voltage. The external rotor concept means that the fan impeller is mounted directly onto the motor's external rotor. |
| Bearing type | ball bearing |
| IP class | IP54 |
| Motor protection | IP54 |
| Motor type | The motor is an electronically commutated external rotor motor with DC operation and high efficiency with low operating noise. The operating electronics are fully integrated into the fan hub. The motor is protected against incorrect polarity and has electronic current limit protection during start-up or blockage. The stator, winding, and circuit board are encapsulated, providing an IP54 protection class. The nominal voltage is 48 V DC with an allowed voltage range of 28–60 V DC. |
