Super Ion Air Knives Remove Dust from Plastic Panels

Conveyor line with static dust problem

One of our distributors reached out to me this week about a static elimination application in Russia.  The end user has the setup shown above, and they are in need of a means to remove dust from the plastic panels on the conveyor.  These panels have a static charge causing ambient dust to adhere to their surfaces.

The main questions for this application were whether we could provide a solution capable of creating a static eliminating blow off for the entire width of the conveyor (approx. 54”), and whether the dust particles can be removed from the working area after removal from the plastic panels.

In order to answer the first question we first had to select a solution, and the Super Ion Air Knife is a near-perfect fit.  We can provide Super Ion Air Knives in any length up to 108”, with a stock length 54” unit available on the shelf.  This was a straightforward recommendation to remove the static from these plastic sheets – install one 111054 54” Super Ion Air Knife on the top and bottom sides of this conveyor to remove the static and blow off the dust.  But, the second question will require a more specialized solution.

When static causes dust to adhere to a surface, removal of the static charge allows the dust to fall off or be blown away, so we were confident that we can remove the static and dust.  But, we then need to vacuum these dust particles away – something we could achieve with a series of Super Air Amplifiers or Line Vacs – which will require some sort of specialized hood.  Fortunately for us, this application already has a vacuum control system with a hood (you can see this in the right side of the photo with a large plastic air duct running to the top and bottom hoods on this conveyor line).

So, problem solved!  We recommended the two Super Ion Air Knives are installed with the airflow aimed at a 45° angle of attack, opposite the direction of travel, and with the airflow aimed into these vacuum hoods.

If you have a similar application or static problem in your facility, give us a call, we’ll be happy to help.
