Static Elimination for Tight Spaces or Areas Sensitive to Airflow

If you’re having problems with static build up on small and/or lightweight materials where even the smallest amount of airflow can disturb the product, EXAIR has the perfect solution, the EXAIR Gen4 Ionizing Point.  The Gen4 Ionizing Point is a single point ionizer that lends itself naturally to winding, rewinding, slitting or a myriad of other applications.  It can even be mounted through the wall of a duct to neutralize static charges in an existing air or conveyance duct.

Gen4 Ion Point 1
EXAIR’s Ion Point In Action

The Gen4 Ionizing Point is very powerful and robust solution that can dissipate 5,000 volts in .24 seconds from 2″ (51mm) away!  The Gen4 Ionizing Point features an electromagnetically shielded high-voltage cable that is armored to protect against abrasion and cuts and its integrated ground design does not require a separate ground connection.  For even more convenience the Gen4 Ionizing Point is replaceable if the point should ever become dull or bent.

Ionizing Point Performance

Its smaller footprint naturally lends itself to installation into the limited space normally associated with smaller applications.  The stainless steel, and replaceable, emitter point is mounted in a saddle that is 1.77″ (45mm) long by 1″ (26mm) wide and includes two .20″ (5mm) mounting holes that are 1.44″ (37mm) apart for easy mounting.

Gen4 Ion Point 3

Gen4 Ionizing Points are supplied power by either the model 7960 power supply which can operate up to two ionizing products or the 7961 that can operate up to four ionizing products.  Both models feature selectable voltage to run on either 115 VAC or 230 VAC.

The Gen4 Ionizing Point is the perfect solution for spot static elimination without air assistance.  Most importantly both the EXAIR Gen4 Ionizing Point and Gen4 power supplies are UL component recognized to US and Canadian safety standards, and are CE and RoHS compliant.

Ionizing Points: A Good Solution in an Air Ducting System for Textile Processing

Model 8299 Ionizing Point
Model 8299 Ionizing Point

Static is all around us. It is caused by non-conductive materials having their electrons “rubbed” from one atom onto another.  With the proliferation of engineered plastics throughout industry static is generated more readily and issues will start to appear when the static voltage gets large enough.  EXAIR has a Static Eliminator product line with many solutions to help solve process issues.

Companies build systems using blowers and fans to generate air flows for various processes. Because of the high noise level normally associated with blowers and fans, they are generally mounted outside or away from the production floor.  To bring the air to the work area, they use ductwork. Systems that involve plastic, wood, glass, or other types of non-conductive material, have a potential for developing static problems.  The Ionizing Points are designed to remove static in small tight areas as well as in air duct systems that already have air moving through them.

I spoke to a customer recently who had a dust collection system in a room where an adhesive is applied to a fabric. The “openness” of the fabric allowed some adhesive to penetrate and land on a 36 inch (0.9 meter) wide conveyor belt.  After the fabric was sprayed, it was conveyed into another room for further processing.  The conveyor belt had to be cleaned continuously to support new fabric as it was being brought in.  The conveying system was long enough to allow the adhesive to dry before it was to receive the next round of material.  The conveyor belt material was such that the adhesive did not stick to it.  (Or so they thought!).  As the adhesive dried, it would “ball up” and harden on the belt and would need to be removed.  To remove the particles, they used a push-pull cleaning method, blowing air through the duct and onto the belt surface to push the dried adhesive into a vacuum hood which pulled the particles into the dust collection system.

The customer started having issues with the contamination level within their fabric. From the nature of how the contamination was acting within the application, the customer had a strong suspicion that static  was causing the contamination issue. The air through the duct could not generate enough lift on the particles for the vacuum system to remove them.  The result was that dried adhesive was transferring onto the fabric.  The customer was concerned that he would have to upgrade his complete push-pull system to continue his production.  He contacted EXAIR for a solution.

In reviewing his room parameters, the customer did not have any compressed air lines going into this room.  This narrowed my search in our Static Eliminator product line to our Ionizing Points, which do not require compressed air. He could place them along the end of the duct to generate ions which will eliminate any static charge present and release the adhesive particles.  He purchased eight Ionizing Points and mounted them 4 inches (10 cm) apart.  As the air was exiting the 36 inch (0.9 meter) wide ductwork, it would pick up the ions, remove the static from the conveyor belt and adhesive, and allow the vacuum flow to lift the particles.  The adhesive remnants could then be picked up by the vacuum system as designed.

If your application already has blower or fan systems and you need to remove static, inserting one or more of the Ionizing Points through the duct wall could be a low cost solution to enable reasonable static elimination. If you have an application that you would like to discuss, contact an Application Engineer for help.
