The automatic anti-static dust blower with snake nozzle creates a large airflow carrying negative and positive ions, blown at high speed, capable of neutralizing the electric charge on the object.

Principle: When the surface of an object is negatively charged, it will attract positive ions in the airflow. Conversely, when the surface is positively charged, it will attract negative ions in the airflow. Thus, static electricity on the surface of the object is neutralized.

In addition, the high-speed airflow will blow away stubborn dust particles on the surface of the object.
