It has been over two years since EXAIR first brought our Gen4 Static Eliminators to market with improved performance, materials and durability. The new design features continue to provide our customers with reliable, rugged and problem solving static eliminators.
More recently our Gen4 product line was completed by integrating these same beneficial features in the Gen4 Ionizing Bars, Gen4 Super Ion Air Knives, and Gen4 Standard Ion Air Knives.
There are two common ways that a Static Eliminator will start to underperform; contamination buildup and point degradation. To create ions from a metal point, a high voltage is needed. With 5,000 volts forcing its way into a confined area, the energy behind making an ion creates a corona field. Any contamination near or around that point will produce a small amount of charred material. The more contamination in the surrounding area, the faster the buildup will occur. Once a sharp point is coated, the ion production begins to decrease.
The other issue is with metal point degradation. With the cycle of heating and cooling, the material will start to lose the sharpness of the point over time. Like a wick used in a candle, you lose a little bit each time. For both methods above, once the point sharpness is reduced, the dissipation time to remove static starts to increase.
For any “forensics” analysis with the Static Eliminators, you should have a model 7905 Static Meter. Besides viewing the ion points, the Static Meter can help determine the severity of the function of the ion points. If cleaning is required, you can use a soft-bristled brush to remove any charred contamination from the point and the base area. Make sure that the power is turned off before cleaning. For resistor-based Static Eliminators, the metal ion pins are replaceable. This is model 901188. This added feature makes a cost-effective way to keeping the points sharp, and the Static Eliminators like new. The video below shows how to clean and replace the ion points.
