Well folks, it’s official, we are right smack dab in the middle of static season. Not even 3 days into the new year, I had already had 2 calls for static elimination help on conveyor applications. Fortunately, I was able to suggest an easy solution for both customers.
One of the customers I spoke to is a pad printer. They needed a way to remove dust and other airborne particles that could settle on the surface to be printed, and create a flawed print. Since they were working with fairly small parts, for their application I recommended a 6″ Super Ion Air Knife and power supply. This will not only eliminate the static charge that is causing the dust to stick in the first place, it will also blow the dust right off the surface of the parts, making a nice clean surface ready for printing on.
The other customer who contacted me makes fabrics for the pulp and paper industry. They needed a way to remove static from a continuously moving web of a very fibrous material. Due to static charges, the web was clinging to the rollers and wrapping around, instead of traveling along the rest of the path. Since the material is still in a fibrous state and not fully bonded at the trouble area, airflow was not wanted, because it would disrupt the web. So, an Ion Bar was a better choice in this application.
The material web is about 100″ across, so a standard length bar would not work. However, Exair does have the capability to manufacture custom length bars up to 120″ overall length. So, they will be able to remove static from across the entire width of the material, using a single continuous Ion Bar and power supply.
If either of these scenarios rings a bell for you, or you have your own static electricity problem that we may be able to help with, please let us know. Feel free to post it in a comment right here on the blog, so other users may also be able to benefit from hearing how a particular application problem was solved.
