DC Fans and Blowers Expanded

A DC fan and blower is a device that uses direct current to turn a propeller. The propeller creates airflow, which can cool electronic equipment or provide ventilation in a room.

At Sunon, DC fans are available in both standard and mini sizes. Standard DC fans range in size from 8 inches to 24 inches, while mini DC fans range in size from 2 inches to 6 inches.

Brushless DC Fans

Sunon offers brushless DC fans, which are composed of a stator and a rotor. The stator is fixed, and the rotor rotates around it. There are no brushes between the rotor and the stator, so there is no sparking and no wear. This makes brushless DC fans more reliable than brush-type DC fans.

Advantages of DC Fans and Blowers

Why would you want to choose a Sunon DC fan or blower over an AC fan or blower? Here are five reasons why:

  1. They’re more efficient than AC fans and blowers.
  2. Their speed can be controlled, which makes them more versatile.
  3. They’re smaller and lighter.
  4. They run quieter.
  5. They last longer.


Sunon DC fans and blowers are used extensively in automotive, gaming & VR, medical, telecom, food and beverage, and industrial applications, including:


Inside the fan or blower, a small electric motor spins a propeller-like blade. The spinning blade draws in air from the surrounding area and forces it through a duct or tube. This air is then blown out the other end of the duct and into the space that needs to be cooled.

Sunon fans and blowers are also used in supply systems, a type of ventilation. These systems use a fan to bring fresh air into a building. The polluted air is expelled through vents or open windows. Supply systems are often used in industrial applications.
