Flexxaire is Born
The Flexxaire story begins in 1983 with Clarence Isert; a local farmer/ inventor. After working in an open cab dozer in the extremes of Alberta weather (+35C in the summer, -40C in the winter), and with his radiator continuously plugging, Clarence decided that a variable pitch fan would solve a lot of problems. After building a number of prototypes, Clarence developed a workable design for a Cat D6D. In 1989, Clarence and a group of local investors joined forces and formed Flexxaire Manufacturing.
