The generic calculation option therefore defines the performance characteristics of the fan using calculation results from Axial or Centrifugal. The performance of a generic fan is based upon volumetric flow rate and blade efficiency (both of which can be determined using the Axial and Centrifugal calculation options), the outlet area of the fan diffuser and the inlet and outlet atmospheric conditions. You calculate the performance characteristics of the blade using either the Axial or Centrifugal calculation option the output data from which you use to calculate the performance of the fan. CalQlata has tried to simplify the subject with the fan calculator and its technical help page on this website. Most technical reference books and related data sites make this subject a little more complicated than it needs to be. and their performance is almost entirely governed by blade design and rotational speed, flow and head characteristics are generally governed by the fan's inlet and/or outlet ducts. Whilst most fan designs (axial, Sirocco, centrifugal, etc.) are suitable for many applications including extraction, distribution, compression, etc.
