As we all know, DC fans are the key cooling equipment for modern industrial machinery. It consists of stator, rotor and commutator. The basic structure is generally composed of a motor, bearings, blades, housing, power plugs and wires. According to different power supply methods, there are two types of motors: DC motors and AC motors. So do you know what to consider when choosing a DC fan?

Speed of DC fan

The speed of the DC axial fan is the same as the power. The higher the speed, the greater the wind, and the better the cooling function. However, high speed will cause high vibration and noise will follow, and the higher the speed, the greater the impact on the service life of the fan.

Material of DC fan

Aluminum and plastic are two popular materials for axial fans in the market. Aluminum fans are generally AC fans,  and AC cooling fans have low cooling performance and small air volume; DC fans are generally made of plastic, and DC fans have higher performance. The DC fan must be able to provide sufficient exhaust. The hot air in the cooling device will work in the reverse direction when the temperature of the hot air is low or the flow of the hot air is relatively small at high temperatures.

Choosing a good brand of DC cooling fan is something that users often overlook when choosing. Many inferior brands of fans will produce a lot of noise due to severe bearing wear after using them for a period of time, which not only affects the service life of the fans, but also upsets you during use. Therefore, it is recommended that you choose high quality Chungfo brand products.
