6 major differences between AC ion fan and DC fan
From the working principle, the ion fan is divided into two types: AC and DC. The DC fan uses a DC generator to work, while the AC fan operates on AC, so how to choose an ion fan? What is the difference between an AC ion fan and a DC ion fan? The editor of Runfengyuan will introduce the 6 major differences between AC ion fans and DC fans.
The appearance of ion fans is mainly to eliminate static electricity in the area and protect components from electrostatic damage and dust particle adsorption. Let's not talk about which is better, AC ion fan or DC ion fan? First of all, let's understand AC ion fan and DC ion fan. The difference between ion fans:
1. The number of discharge needles is different
1. AC ion fan: one
2. DC ion fan: two pairs appear
From the discharge method, the AC ion fan only needs one discharge needle to release positive and negative ions, while the DC ion fan needs at least two discharge needles to release positive and negative ions, one to release positive ions and one to release negative ions, so DC ions The discharge needles of the fan are often paired in an even number.
Second, the ion concentration produced is different
1. AC ion fan: low ion concentration
2. DC ion fan: high ion concentration
The number of discharge needles of the DC ion fan is obviously more than that of the AC ion fan, so the ion concentration released by the DC ion fan is obviously higher than that of the AC ion fan. Then, it can be seen from the side door that the static removal speed of the DC ion fan is slightly higher than that of the AC ion fan.
Three, the ion balance is different
1. AC ion fan: high ion balance
2. DC ion fan: low ion balance
Since the needle position of the DC ion fan to generate positive ions and negative ions is fixed, the charge on the target surface is uneven, that is to say, the ion balance of the DC ion fan is lower than that of the AC ion fan. If the discharge needle is affected by the environment or polluted, the tip of the discharge needle will be worn for a long time, which will aggravate the damage to the ion balance, even if it is cleaned later, it will not improve.
Fourth, the ion release distance is different
1. AC ion fan: short ion release distance
2. DC ion fan: long ion release distance
In other words, the AC ion fan is suitable for removing static electricity in a short distance range, generally within 30cm. The DC ion fan has a longer release distance and a longer applicable distance.
5. Security
1. AC ion fan: poor safety
2. DC ion fan: high safety
The DC ion fan generates weak current, which basically has no effect on the human body. The AC ion fan generates a large current, which can easily cause harm to the human body.
6. Service life of transformer
1. AC ion fan: the transformer has a short service life
2. DC ion fan: long service life of the transformer
The voltage fluctuation in the built-in transformer of the AC ion fan is relatively large, the damage to the transformer is relatively large, and the service life is relatively short. The built-in transformer of the DC ion fan does not have too much voltage fluctuation, so the service life will be very long.
