Summary
- Air knives are devices that blow air in a thin sheet, and are used in industrial settings to blow air over surfaces to clear them of dust or debris.
- They work by combining air from a compressor or blower with the Coandă effect, which maintains the flow of the air.
- YouTuber This Old Tony has made a video showing how to make an air knife, although he refers to his rounded design as an air amplifier.
- Commenters on the video pointed out that the round design is usually called an air operated conveyor, and explained their usage in industry.
- Also mentioned was the similarity between the function of air knives and “bladeless” fans, such as those produced by Dyson.
