What is a X°Air air knife? The X°Air air knife uses the COANDA effect to deliver high velocity air with a small volume of compressed air. The amplification coefficient is 30:1, which means that the consumption of compressed air is reduced by 40 %to 90% and sound levels by 10 dBA as compared to classic blowing methods (pierced pipes, nozzles etc.). It takes just a couple of weeks to make up for the initial cost of the air knife. The amplification ration of the X°Air air knife is 30:1. |

The compressed air is injected through an orifice (1) into the chamber (2), and comes out of the slot (3) at a rapid pace, inducing an flow (4) called an "entrained" flow. |
