MAC Equipment is marking a major milestone by celebrating its 40th anniversary. In 1969, Gary and Virginia McDaniel established MAC Equipment in Sabetha, Kan. The company pioneered the development of dust collection and clean air systems based on the Clean Air Act of 1970. For four decades, MAC has demonstrated the ability to respond and react to changes in the industry. Gary McDaniel retired in 1998 and sold the business to George K. Baum and Co., allowing for continued growth in both dust collection and pneumatic conveying during the next decade. This dramatic growth in such a short span of time caught the attention of Clyde Process Solutions PLC, which acquired MAC in 2007. The acquisition created a global presence for both MAC and Clyde technologies that continues today. MAC Equipment employs more than 350 people in North America.
