Turbo Cooling Fan 12V DC 4020

Product Description :

The DC 12V 4020 Blower Fan is a compact brushless turbo fan designed to deliver strong, concentrated airflow in small spaces where precision cooling is essential. Measuring 40×40×20mm, this fan is widely used in 3D printers, CNC machines, extruders, and electronic components. Its 2-pin connector makes it easy to wire and install, while the brushless design ensures long-lasting durability, stable operation, and quiet performance.

Unlike standard axial fans, the 4020 blower type pushes air through a side outlet, making it ideal for applications that require directed cooling such as hotend nozzles or stepper motor drivers. This feature is particularly useful in 3D printing, where targeted airflow can significantly improve extrusion consistency and prevent heat buildup around sensitive parts.

The fan consumes only 0.1A ±10%, making it both energy-efficient and reliable. Its brushless motor technology reduces wear, increases lifespan, and ensures smoother rotation compared to traditional brushed fans.

With its versatile design, this 12V blower fan is not only used in 3D printers and CNC systems but also in electronics cooling, robotics projects, and DIY automation builds. Wherever compact yet powerful cooling is required, the 4020 fan proves to be an excellent choice.
