EVOLVENT ® pressure-chamber nozzle system the airflow is compressed in the pressure chamber and distributed evenly by the nozzle over the entire air blow-out width. The airflow is accelerated by the concave nozzle cheeks to such an extent, that a concentrated, induction-poor and against the outside air directed air curtain develops. For the same screening effect as with the conventional lamella system, less air is clearly needed and consequently less energy.
