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.
For customer support and problem solving, you should have a
model 7905 Static Meter and 901188 replacement emitter points in stock.
In most applications, when a customer complains about performance issues with
Static Eliminators, the most common issue is dirty ion pins that just needs
to be cleaned. If you have other issues with the Gen4 Static
Eliminators, please contact me, Tyler, or Neal.
