Principle
As shown in the figure on the left, after the compressed air (1) enters the air knife, it is blown out at a high speed by an airflow sheet (2) with a thickness of only 0.05 mm. Through the principle of the Coanda effect and the special geometry of the air knife, the air curtain of this sheet can drain the maximum flow. 30 to 40 times the environment (3), and a thin layer of high-strength, atmospheric impact air curtain is formed, and the strength of the air curtain is very uniform
