Neutralising static electricity with or without compressed air? What is the difference?

Gen4 Super Ion Air Knife - deionisation with compressed air

The air knife combines ionisation with airflow to quickly remove static charges and contaminants over large surfaces, moving parts and hard-to-reach areas.

Compressed air flows through an inlet (1) into the plenum chamber of the Gen4 Super Ion Air Knife. The flow is directed into a precise, slit-shaped opening. As the primary airflow passes out, it forms a smooth air blade along its entire length, which instantly entrains the surrounding air (2). An electric Gen4 ionising bar (3) fills the air curtain with positive and negative charges. The airflow of these static elimination ions to the product surface (4), where it instantly neutralises static electricity and blows away dust and other particles.

Gen4 Ionising Bar - deionisation without compressed air

Ideal for use on delicate or lightweight materials, which may be adversely affected by an air flow. Compact and efficient solution for close-range applications.

The electromagnetically shielded power cable (1) conducts 5 kVrms from the power supply to each inductively coupled stainless steel emitter tip (2) on the Gen4 Ionising Bar. An integrated ground wire (3) in the power cable creates a discharge path from the emitter tips to the rod body (4). The discharge at each emitter charges the gas molecules in the surrounding air, resulting in a flow of positively and negatively charged ions (5). If the material surface has a negative charge, it attracts the positive ions from the Gen4 Ionizing Bar and becomes balanced or neutralised. If the material surface has a positive charge, it attracts the negative ions from the Gen4 Ionizing Bar and becomes balanced or neutralised.
