German term or phrase:Druckerhöhung
In an axial fan: "Ein Vorleitrad bewirkt eine Veränderung der nutzbaren Druckerhöhung des Ventilators" - so positioning a guide vane/stator preceding the rotor in a fan has the effect of changing the "nutzbaren Druckerhöhung des Ventilators" - what is this usable/useful factor in a axial/tunnel fan? Any help really appreciated!
