A Breakthrough in Air Knife Technology:
Unique Protruding Leading Edge Leads to a More Controlled Air Stream
The leading edge of the WindJet Air Knife extends 1/8″ beyond the air slot along the length of the knife. The air flow out of the knife is a straight stream that retains its integrity in a more controlled manner.
WindJet Air Knife Dimensions. The extended edge also improves the air entrainment around the air knife body. Operating on the principles of the Coanda effect and air entrainment, the WindJet Air Knife provides a steady, consistent, high-volume stream of air. The longer edge of the air knife takes advantage of the Coanda effect, which induces the supplied air to attach itself to the surface of the knife. The integrity of the air stream is maintained further downstream and a condition conducive to the entraining of ambient air is present, increasing the total volume of air (see Figure 2). |

The resulting uniform, high volume, constant air stream along the entire knife length eliminates spotting or blotching for a higher quality, consistent dryoff process.
Another advantage of the knife’s leading edge is that it helps application setup. The extended edge provides a visual guide to indicate the path of the air stream. It literally points out the direction of the flow so you can accurately position the knife for optimum performance.
Other performance-enhancing features include:
- A teardrop shape to give the exiting air stream a higher velocity
- High quality end caps to eliminate leaks and ensure high operating efficiencies
- Corrosion-resistant finish
- A choice of two air slot sizes: .040″ for a higher impact air stream and .060″ for a higher flow
- A choice of lengths: 6″, 12″, 18″, 24″, 30″ and 36″. Custom lengths are also available
- A 3″ flanged air inlet is designed with a threaded mounting insert
