Compressed air-powered air knives

Compressed air-powered air knives

There have always been various blowing appliances. Air knives and nozzles for compressed air blowing range from domestic pipe with holes to engineering high pressure air knives. In order to achieve maximum efficiency with compressed air, many compressed air knife manufacturers use the Coandă effect to improve the design of compressed air knives rather than other types of knives and nozzles. Although compressed air is much less efficient for low-pressure blowing than a blower, the Coanda air knife draws ambient air into the high-speed air stream to enhance blowing.
