Maintaining its focus on the customer, Danair added more product lines to assist customers, including jacks and hydraulic power units, and continued to grow until they were sold to Tronco. The company changed its name to Tronair after the acquisition and moved from a 5,000 square foot facility in Maumee, Ohio to its present location a 300,000 square foot facility in Swanton, a suburb of Toledo, Ohio.
