What is an Ionising gun?

Ionising Gun

An ionising gun, often referred to as an ESD ionizing gun or air ionizer, is a device designed to neutralize static electric charges on a variety of surfaces and materials. This tool is essential in preventing electrostatic discharge (ESD), which can damage electronic components, ignite flammable mixtures, or cause materials to stick together.

How It Works

Ionising guns operate by emitting a balanced stream of positive and negative ions. When directed towards a charged surface, these ions neutralize static charges, thereby reducing the risk of ESD. The ionizing effect is achieved through a high-voltage discharge that creates a cloud of ions in the surrounding air.


Ionising guns find widespread use in various industries, including electronics manufacturing, pharmaceuticals, and cleanroom environments. Their ability to effectively neutralize static charges makes them invaluable for:

  • Preventing ESD damage during the assembly of electronic components.
  • Reducing particle contamination in cleanrooms.
  • Improving packaging processes by eliminating static that can attract dust or cause materials to cling.


Using ionising guns offers several benefits, such as:

  • Enhanced Safety: They help prevent fires and explosions in environments with flammable gases or particles.
  • Improved Product Quality: By eliminating static, they reduce the risk of contamination and damage to sensitive electronic components.
  • Increased Efficiency: They facilitate smoother manufacturing and packaging processes by preventing materials from sticking together.


When implementing ionising guns in a workplace, it's important to consider:

  • The need for regular calibration and maintenance to ensure effectiveness.
  • Potential ozone production, which can be a byproduct of the ionization process.
  • Proper positioning and operation to maximize ion distribution and neutralization.
