Principle and application scope of DC ion fan

The HM-101DC miniature DC ion fan can generate a large amount of airflow with positive and negative charges, which can neutralize the positive and negative charges carried on objects. When the surface charge of an object is negative, it attracts positive charges from the airflow; When the surface of an object carries a positive charge, it will attract negative charges in the airflow. When equal amounts of positive and negative charges come into contact, electrical neutrality can be achieved. DC ion fans are suitable for providing a wide range of anti-static areas, fast anti-static time, and stable ion balance voltage in clean rooms.
The HM-101DC miniature DC ion fan can eliminate or neutralize static electricity in a wide range of concentrated targets or hard to contact areas. It is an ideal static eliminator for precision electronic products, electronic assembly, pharmaceutical manufacturing assembly, packaging, and small product molding. Mainly applicable to industries such as pharmaceutical equipment manufacturing, electronic assembly production lines, microelectronics manufacturing, and precision electronic assembly production lines for LED, LCD, PCB, etc.

6、 Safety instructions

1. The socket connecting the fan must be reliably grounded.
2. Do not insert anything into the air outlet.
3. Do not operate the fan in flammable and explosive environments.
4. Unauthorized repairs are not allowed.

7、 Maintenance

1. Ionic fans are designed with the goal of regular maintenance and low repair
When using an ion fan, the ion needle of the ion fan continuously ionizes the air and generates positive and negative charges, making it easy for the ion needle to adsorb small dust particles in the air, thereby reducing the effectiveness of the fan in removing static electricity. Therefore, it is necessary to regularly clean and maintain the ion fan (the maintenance cycle depends on the usage environment)
Maintenance items: Cleaning of the launch head, calibration of ion balance, calibration of electrostatic discharge time. Clean the launch head at least once every two weeks, and regularly calibrate the ion balance and electrostatic discharge time to ensure the normal operation of the ion fan.
1. Cleaning of the transmitter
To clean the emission point of the transmitter, first disconnect the power supply of the ion fan and clean the emission needle with a cotton swab or dust-free cloth dipped in alcohol; Until the ion emission needle tip is cleaned thoroughly, at least once every two weeks.
2. Cleaning of air inlet and outlet
The air inlet network and ionized air outlet network should be kept clean to prevent blockage of airflow, and can be cleaned with a soft bristled brush or compressed air.
3. Ionic balance test
Measure ion balance (residual voltage) using an electrostatic analyzer.
4. Static elimination time test
Measure the static elimination time using an electrostatic analyzer.
5. The ion fan is designed to have a stable and fixed output of ions. Due to factors such as voltage fluctuations and humidity in the ambient air, there may be a deviation in ion balance (residual voltage). Offset standard: 0V ± 10V. If there is a significant deviation between the static elimination time and residual voltage, it should be sent back to the factory for calibration.
