Air knife

The air blade, a nozzle with a rectangular cross -section, of the outlet a fast air stream. The air jet resembles the shape of a blade approximately 0.3 cm in height and 10 to 150 cm in width and is a laminar flow.

A strong fan transported as much air volume with little pressure. In the air, the blade of the cross-section becomes smaller and smaller. According to the Bernoulli's equation results in the outlet opening of a large flow rate. With this fast paced air jet objects are in the industry cleaned or light parts separated from heavier.

There are also operated with compressed air the air blades, where a high input pressure (about 6 bar) exits through a very narrow gap and a lot of air sucks from the environment, at least 40 -fold increases the air flow.
