The generic calculation option therefore defines the performance characteristics of the fan using calculation results from axial or centrifugal.
There are a number of fan types.
Axial centrifugal fan blade design whilst these calculation options are primarily for the performance characteristics of an impeller via blade configuration they also offer the performance effects of an external casing.
