This week I worked with a gentleman, who was having a problem cleaning a honeycomb web after a sawing operation. The honeycomb was a paper based material, and the sawing operation would create a large amount of dust. This dust filled his honeycomb, which made the product appear inconsistent to his customer on incoming inspections. This was leading to the customer questioning the quality of the product.
His process featured a blower that was incredibly noisy and still left some material on the product. During the winter, the problem was further exasperated by the dry air, which led to the dust being statically charged and clinging to the honeycomb even more. In spite of his quality and production issues, the customer was looking to expand his production to meet demand. The blower he was using had been custom-made for his machine, so he was open to any ideas. Also, the blower had no way of removing static electricity from the material.
I recommended he use an 84″ Super Ion Air Knife to clean his 80″ honeycomb web. The customer mounted the air knife perpendicular to the surface of the honeycomb 4″ away from the surface. One of my concerns with the operation was creating even flow. To do this on a long span, I recommended he use have the plumbing kit installed at EXAIR, which allows the air knife to create an even flow along the length of the knife y preventing any restrictions which may occur from poorly sized inlet fittings, hose or tube. The Super Ion Air Knife cleaned the honey comb with ease, while maintaining a quiet 69 dBA, and without the expensive maintenance required by the blower.
