Chicago Blower Corporation has been designing and manufacturing pre-engineered and heavy duty fans and blowers for over 65 years. Our privately held company was founded in February 1947 and has been growing ever since. What began with only four employees in a small Chicago factory grew into our vast Glendale Heights plant that is the center of CBC’s operations where engineering, fabrication, testing, inside sales, accounting, purchasing, and marketing all work together to maintain our reputation for exceptional performance and reliability.
