Summary

[edit]
Description
English: Modification of the fan characteristics and of the operating point for the altitude variation. Example: Axial fan at see level (air density 1.118 kg/m3) and at 400 Meter altitude (air density 0.722 kg/m3). The 4000-meter characteristics was calculated from the see-level characteristics using the fan laws.
Deutsch:
Verschiebung der Lüfterkennlinie und des Arbeitspunktes bei einer Änderung der Höhe über Meeresspiegel. Beispiel: Axiallüfter am Meeresniveau (Luftdichte 1.118 kg/m3) und in 4000 Meter Höhe (Luftdichte 0.722 kg/m3). Die 4000 Meter -Kennlinie wurde aus der Kennlinie am Meeresniveau berechnet durch Anwendung der Lüftergesetze.
