I saw in another post that the Huber Reversable fan Company was going out of business. I knew Herm Huber: who invented the fan back in the 50's after running dozer in a strip mine. He passed away several years ago. His daughter has tried to keep the company going but most of the new dozers have cabs and demand for their fan has fallen off. I stopped there today and the place is almost all cleaned out. The scrappers are coming for the machines they used to make the fans tommorrow. The machines are old and don't meet OSHA, she said they are worth more as scrap then machines. It's sad another made in USA product dieing out
