DC and AC Ionizing Fans
Ionizing fans are used to efficiently eliminate static electricity and prevent electrostatic discharge (ESD) from damaging precision electronic components, production processes, and product quality. Their core function is to neutralize the surface charge of objects by generating a stream of positive and negative ions, thereby preventing static electricity from attracting dust, damaging components, or interfering with production processes.
Static Electricity Hazards and the Necessity of Elimination
Component Damage: ESD can directly damage or burn out electronic components, leading to product failure.
Dust Adsorption: Static electricity attracts dust, contaminating product surfaces and affecting the performance of precision components such as optical devices and semiconductors.
Production Interference: The electromagnetic field generated by ESD may interfere with equipment operation, leading to production interruptions or data errors.
Hidden Costs: Minor static damage may not be immediately detected, leading to rework or customer complaints, increasing company losses.
Ionizing Fan Working Principle
Air Ionization: A built-in high-voltage generator ionizes air, producing a large number of positive and negative ions.
Airflow Delivery: The fan blows the ionized air stream towards the target object's surface.
Charge Neutralization: When an object is positively charged, it attracts negative ions in the airflow to neutralize it. When an object carries a negative charge, it attracts positive ions from the airflow to neutralize it. Additional functions: Some models feature dust removal, network monitoring, and automatic cleaning functions, improving maintenance efficiency. Core application scenarios:
* Electronics manufacturing: ESD protection in integrated circuit board printing, chip packaging, hard drive assembly, etc.
* Precision industry: Fields with high cleanliness requirements, such as optical instruments, semiconductor production lines, and medical equipment.
* Materials processing: Static electricity control in plastic film slitting, resin molding, and spraying processes.
* Food and pharmaceutical: Preventing foreign matter contamination due to static electricity, ensuring hygiene and safety.
6. Advantages of AC ion fans: They are unaffected by the environment, have strong airflow, and a long lifespan.
7. Weaknesses of AC ion fans: They operate at 220V AC and have a power rating of 45W; they consume more electricity, are larger and heavier, produce more ozone, and generate more noise.
