Gen4 Ionizing Bars

Low cost Ionizing Bars eliminate static cling! Compact, rugged design for industrial applications.

What Is The Gen4 Ionizing Bar?

EXAIR’s Gen4 Ionizing Bar is engineered to perform up to 25% better than the previous models for applications where the bar is mounted within 51mm (2”) of the surface it is treating. It has also been designed to perform well 100% farther away by providing static elimination up to 102mm (4”) from a charged surface. Gen4 Ionizing Bars eliminate static electricity on paper, film and plastics that can attract dust and foreign materials, ruin product appearance, produce tearing or jamming, and zap personnel. The electrically powered Gen4 Ionizing Bar is compact, allowing it to fit in the confined spaces of machinery, where the charge is generated. A high concentration of positive and negative ions produce fast static decay, neutralising any surface within 102mm (4”) of the bar.

The unique design of the shockless Gen4 Ionizing Bar offers improved performance and reliability in industrial applications. Life expectancy has been extended by insertion moulding the stainless steel ion emitters into a durable engineered polymer. There are no openings or grooves to accumulate dirt that could cause shorting or arcing. A 5kV power source provides high performance, eliminating frequent burnouts commonly associated with traditional 7kV bars.

The Gen4 Ionizing Bar includes a 1.52m (5-foot) shielded cable with ground. A mounting flange is provided for easy installation and all components are fully assembled. Standard lengths up to 108″ (2743mm) are available from stock and special lengths up to 119″ (3.05m) are available by special order. EXAIR Model 7960 or 7961 Gen4 Power Supply (5kV) is required for bar operation.

The ability to eliminate static can be greatly improved when attaching the Super Air Knife to the Gen4 Ionizing Bar. The Gen4 Super Ion Air Knife propels the static neutralising ions over a larger area, which is ideal for high speed, high charge applications. Air delivery can also remove dust and clean the product surface.

How the Gen4 Ionizing Bar Works?

The electromagnetically shielded power cable (1) carries the 5kVrms power supply output to each inductively coupled stainless steel emitter point (2) of the Gen4 Ionizing Bar. An integrated ground wire within the power cable creates a discharge path from the emitter points to the bar channel (3). The discharge at each emitter charges the molecules of the gases of the surrounding room air, resulting in a shower of ions that are positively and negatively charged (4). If the material surface has a negative charge, it will attract the positive ions from the Gen4 Ionizing Bar and become balanced or neutralised. If the material surface has a positive charge, it will attract the negative ions from the Gen4 Ionizing Bar to become balanced or neutralised.

The voltage potential at each emitter is high enough to ionise the surrounding air without generating a shock when any of the emitters are touched.

Gen4 Power Supplies
Exair Model 7960 or 7961 Gen4 Power Supply (5 kv) is required for ioniser operation. Selectable voltage: for use with all Gen4 Static Eliminators

The Two and Four Outlet Gen4 Power Supplies have selectable voltage, which allows you to choose input voltages of 115VAC or 230VAC. The modular cable with electromagnetic shielding protects sensitive electronics against electromagnetic interference while easing connections and routing. An integrated fuse on the primary protects against voltage spikes.
