A customer of ours had an application where they needed to cool and dry parts on two conveyors that ran side by side. A single 36″ Super Air Knife was chosen to provide coverage over the full width and to simplify the air plumbing and installation. As we learned more about the application, it was discovered that there was 10″ section in the center where the the two conveyors butted up, where no parts would pass through, and hence no air was needed.
Fortunately, the EXAIR Super Air Knives can be supplied with custom shim designs to match the air flow requirements of the application. These shims can be of various thicknesses to increase/decrease the air flow, of alternate materials such as a stainless steel shim in an aluminum air knife to increase the temperature range, or as in this case, designed to provide specific air flow patterns.
By utilizing the special shim design, it is estimated to save $865 per shift per year in compressed air costs versus the standard configuration. That is a significant savings, and using less compressed air is high on everyone’s priority list.

EXAIR manufactures 3 different types of air knives, in 4 different materials, up to 108″ in length.
