AC, DC, EC fans Features

When it comes to cooling fans, it is estimated that everyone is very familiar with them. They are indispensable in our life, such as household appliances, electronic products, digital computers, medical equipment, etc. They will be used as long as they need cooling and exhausting. Cooling fans can be divided into AC fans, DC fans and EC fans. Here, I will explain the difference between AC / DC / EC fans:

AC fan is what we call AC cooling fan. The principle and manufacturing method of this kind of fan are very simple. Its characteristic is that the power frequency is fixed and will not change with the positive and negative voltage.

DC fan and EC fan belong to DC cooling fan, but there are some differences between them. A simple summary: DC input is DC, EC can input AC, which converts AC into DC.

Advantages of AC fan:

1. Provide stable and continuous air volume.

2. Hot air can be discharged and colder air can be inhaled.

Advantages of DC fan:

1. Minimal electromagnetic interference.

2. Low energy consumption.

Advantages of EC fan:

It has the characteristics of high intelligence, high energy saving, high efficiency, long service life, low vibration, low noise and continuous work.

We are Chungfo, a professional manufacturer of cooling fans. We prodece DC axial fan, DC blower fan, DC frameless fan, AC fan, AC / DC cross flow fan, EC fan and so on.

DC axial fan is made of PBT material. When it is working normally, the service life can be as high as 50,000 hours. The internal structure of the DC has a transformer and a main control board, which will not be affected by voltage fluctuations, so it is used Longer life.

High speed axial fan, its rotor contains DC cooling fan blades, which are the source of air activity, the fan axis, and are used to support the rolling of the balanced fan blades, the rotor magnetic ring, and permanent magnets. Ring frame, fixed magnetic ring.

In addition, DC cooling fan also includes a supporting spring, through which all the components and motors of the tube rolling are fixed, the rolling direction is produced, and the key to the size of the rolling speed can be activated. Its speed regulating performance is good, and the control is simple.
