EXAIR manufactures a whole line of products dedicated entirely to the purpose of neutralizing static charge which can interfere with many manufacturing processes. EXAIR's Static Eliminators
use the same compressed air technology as many of our other products, with the added element of ionization to eliminate static charge on the target surface. All of our ionizers will produce both positive and negative ions, to neutralize either charge polarity that may be present on the target surface.
The Super Ion Air Knife
and Standard Ion Air Knife
are often used in moving web applications where static charges attract dust particles which can interfere with the way a finish or coating is applied on a product. They simultaneously neutralize the charge that is holding the dust on the surface and provide a high-velocity, uniform curtain of air to remove that dust from the surface. The Super Ion Air Knife and Standard Ion Air Knife are EXAIR's two Static Elimination products with the widest coverage area. They are pneumatically identical to their non-ionizing counterparts, the Super Air Knife
and Standard Air Knife
. However, they have the added benefit of static elimination with the attachment of the Ionizing Bar to them. Thus, they are best suited for applications having a large surface area to deionize and remove dust and debris from.
In sensitive applications where a strong airflow would not be desirable but ionization is still needed, the Ionizing Bar
may be a better choice. It will provide a linear cloud of ions approx 2-3" away from the line of emitter points, providing effective static elimination without disturbing the target surface. The Ionizing Bar is simply the ionization component of the Super Ion Air Knife and Standard Ion Air Knife. It allows a wide area of ionization where airflow is not needed or would be problematic. It consists of a straight line of emitter points encased in a thermoplastic material, held together in an aluminum housing. The Ionizing Bar is available in all the same standard lengths as the Ion Air Knives, from 3" up to 54". However, custom lengths up to 119" effective length are also available. The Ionizing Bar has a very small profile, so it will fit well inside tight spaces, such as printers and sheet cutters.
The Ion Air Jet
, Stay Set Ion Air Jet
, and Ion Air Cannon
work similarly to the Ion Air Knives, but they provide a conical airflow pattern as opposed to a linear one. Also, there is only one ion emitter point, since the airflow is more centralized. These products can be fixed over a web or directed at a stationary surface.
For manual operations, EXAIR offers the Ion Air Gun
. It operates nearly identical to the Ion Air Jet, but it has a thumb-activated trigger to allow the user to control the on/off of the airflow. It is designed to be handheld, so the user can adjust both the timing and orientation of the airflow, to precisely target a particular surface.
As with the Ion Air Knives, the conical airflow devices also have an airless counterpart, the Ionizing Point
. It is the smallest Static Eliminator that EXAIR offers. It consists of a single emitter point attached to a cable which connects it to the power supply, and a mounting bracket. It has no compressed air assistance. Thus, it is best used in spot-ionization applications such as winding or slitting operations. It will produce an ion cloud about 2-3" in diameter, containing both positive and negative ions. The Ionizing Point is designed to be used in very small-scale applications where airflow is not needed.
In order to provide the ionization, all of EXAIR's Static Eliminators require a power supply
to deliver the needed voltage to the emitter points. Power Supplies are available in 115V or 230V models, with two or four outlets. They provide 5000V of AC power to each ionizer product connected to it.
One accessory that EXAIR has available to help users determine whether they have a static problem, and target the source, is the Static Meter
. It gives a digital readout of the charge measured on surfaces 1" from the sensor, within a +/- 20kV range.
