AC ion fan and DC ion fan
AC ion fan and DC ion fan which is better?
In the current market, divided from the discharge method, it is divided into two kinds of AC and DC ion fan.
For the time being, what is better than AC ion fan and DC ion fan? Let us first briefly understand the difference between AC ion fan and DC ion fan.
Ion blowers generate ions through high-voltage electric shock through the discharge needle, generating positive and negative ions, thereby neutralizing electrostatic ions, to achieve the effect of static electricity. For the AC ion fan, only one discharge needle is required, and the purpose of discharging the static electricity is achieved by alternately appearing positive and negative ions. In the case of a DC ion fan, two discharge needles are required, one to release positive ions and one to release negative ions. In other words, it takes two to release the positive and negative ions at the same time.
First, the number of discharge needles is different
1 AC ion fan: one
2 DC ion fan: two pairings appear
From the discharge mode, the AC ion blower only needs one discharge needle to release the positive and negative ions, while the DC ion fan needs to release at least two discharge needles to discharge positive and negative ions, one release positive ion and one release negative ion, so DC ion The discharge needles of the fan are often presented as even-numbered pairs.
Second, the resulting ion concentration 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. Therefore, the ion concentration released by the DC ion fan is obviously higher than that of the AC ion fan. Then, from the side door, it can be shown that the static electricity removal speed of the DC ion fan is slightly higher than that of the AC ion fan.
Third, the degree of ion balance is different
1 AC ion fan: high ion balance
2 DC ion fan: low ion balance
Because the pin position of the positive and negative ions generated by the DC ion fan is fixed, the charge on the target surface is not uniform, that is, 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 if it is contaminated, the needle will be worn for a long time and the ion balance will be exacerbated. Even if the post-cleaning is not improved.
TAG: By the way, there is a KESD ion blower KF-21AW with automatic cleaning function, which can greatly reduce the cost of ion fan maintenance.
IV. Ion release distance
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 within a short distance, generally within 30cm. The DC ion fan has a longer release distance and a longer application distance.
1 AC ion fan: poor safety
2 DC ion fan: high safety
DC ion fans produce weak currents that have little effect on the human body. AC ion blowers generate large currents, which can easily cause harm to the human body.
Sixth, transformer service life
1 AC ion fan: short transformer life
2 DC ion fan: long service life of transformer
AC voltage fan built-in transformer voltage fluctuations are relatively large, relatively large damage to the transformer, the service life is relatively short. The built-in transformer of DC ion fan does not have much voltage fluctuations, so the service life will be very long.
From the above points of view, the AC ion fan and the DC ion fan each have their own advantages and disadvantages. The other party's advantage is just its own short board. Therefore, these two types of ion blowers often appear on the market at the same time. It is often necessary to take each one, and through comprehensive trade-offs, which type to choose is most suitable.
