A1: Firstly, please kindly confirm which type of fan you need: DC, AC or EC fan.

Secondly, confirm the main points: size, voltage, speed/airflow, lead wire, lifespan.

Then, consider your product inlet & outlet, choose axial fan or blower fan.

Axial fan blows air along the axis and blades, while blower fan blows air from the fan hole. Airflow of axial fan is powerful, while static pressure of blower is stronger.
