I apologize, but I couldn't locate specific technical details for the ebm-papst 1PH8912-1AB64-0AA0 and 1PH8902-1AE00-0AA0 axial cooling fans. These models are part of Siemens' 1PH8902 and 1PH8912 series, typically used in industrial applications such as spindle motors and machine tool cooling systems.
For precise specifications like airflow, RPM, power consumption, and noise levels, I recommend referring to the official Siemens documentation or contacting Siemens support directly. If you need assistance with alternative fan models or further information, feel free to ask!
