A series of Fan Courses was developed by Chicago Blower to provide an introduction to fan selection and engineering. These courses are geared to fan users and specifiers who would appreciate a simplified, helpful guide rather than reference material for graduate fan engineers.

Unless you are only interested in a specific aspect of fan engineering covered by one of the other courses, you should request "Course 100 - Fan Selection". It takes the mystery out of blade types, fan sizing and industry performance tables.
