Keeping Insulation From Clinging To Refrigerator Shells

A sheet metal company is a contractor for a major appliance manufacturer who is building refrigerators. The manufacturer is drilling holes into the refrigerator housing after it has been double walled and filled with insulation. The insulation is being drilled out of the holes and is sticking to the housing due to a static charge. They have purchased (4) Model 112006 6" (152mm) Super Ion Air Knives to place at the drilling operations to keep the housings clean.
