As mentioned in other blogs and articles, one of the key indicators of a well-made and properly designed compressed air operated air knife is relatively even flow across its length.
When you realize that you are dealing with very small air gaps over a long length, the tolerance and care required to manufacturer and assemble such products can be challenging.
One testament to the quality of Nex Flow® air knives, in particular the X-stream® Air Blade® air knives is that they are fully anodized. That process alone, if not done properly can impact the gap tolerance over even short lengths.
Nex Flow® air knives, (and in fact all aluminum material products) are anodized so there is proper protection for the product in an industrial environment. Most other air knife produces simply are incapable of doing this well, and most do not. If not done properly it can effect even flow and even proper flow from the small gaps existing the air knife (and other air amplification products).
In an article “Multilayer Blade-Coating Fabrication of Methylammonium-Free Perovskite Photovoltaic Modules with 66 cm2 Active Area” by Maximilian Ernst, Jan-Philipp Herterich, Christoph Margenfeld, Markus Kohlstädt, and Uli Würfel”, Nex Flow® is referenced in the experimental section where the 6” Model 10006X X-Stream® Air Blade® air knife was used with nitrogen.
Nex Flow® quality and producing even flow is very important. In fact subsequent to the article when another supplier was used by mistake, they returned hose units to correct the error when they could not get the same, necessary even flow from the poor copy.
We are privileged to be part of these and other research projects that help to confirm the value of Nex Flow® and welcome the opportunity to be part of many more.
