One application for small compressed air operated air knives or flat nozzles is to assist in keeping the lens of cameras clean as in the picture shown. In dirty environments, sticky particulate can be floating around in the atmosphere which can settle onto, and interfere with cameras used in production applications. A small blast of amplified air flow over the lens from the air knife or flat nozzle will keep the lens clean.
In one outdoor application air knives are used to keep camera lenses dry when it rains. For outdoor use stainless steel air knives are used.
While excellent for keeping the lens clean, using the technology to clean after a dirt buildup may be limited if the material is sticky and requires a higher force to remove. Similarly, if dirt is hurling toward the lens from splashing material, the air will not necessarily be effective as a barrier. But except for these conditions, air knives or flat nozzles are ideal.
