Overview of different types of ion fans
Abstract: The electronics industry is the production of high-precision components. The impact of static electricity on the electronics industry is the most fundamental and most lethal.
As we all know, there are many types of ion fans, and the different types of ion fans certainly have differences. The following small series introduces the characteristics and comparison of different styles of ion fan:
1. AC ion fan:
A, simple design and low cost;
B, stable
C. The sine wave has low ionization efficiency and is not suitable for occasions requiring rapid neutralization;
D. Different positive page ionization energy makes ionization balance work difficult;
E. The positive neutralization of positive and negative ions alternately with a period of 1/100 or 1/120 second (50 or 60 Hz) ions will further reduce efficiency and require high wind compensation;
F, due to low efficiency, the need for a larger voltage to generate enough ions, will cause a lot of particles, is not conducive to a strict dust-free environment.
2. DC ion fan:
A. Continuous high pressure uses high ionization efficiency and can handle rapid neutralization needs;
B, can use a lower voltage, suitable for clean room use;
C. Ability to use automatic measurement and feedback to control ionization balance;
D. Complex control circuits are needed to ensure the balance of positive and negative ions.
3, pulsed DC ion fan
A. The ion population generated by the pulse reduces the natural neutralization. Allow the ionizer to leave the protected object farther (can pass 5 meters);
B. It is most commonly used in dust-free workshops where low air flow may be required;
C, the pulse time can be adjusted to suit the airflow or distance requirements of the environment;
D. Pulse waves cause "voltageswing" voltage changes that may be detrimental to some devices.
