Excel Dryer sells about $40 million worth of electric hand dryers each year. Excel’s products can be found in airports, restaurants, and public restrooms across the United States. Most of the parts the company uses come from U.S. suppliers. But the motors and controllers have long come from China. No other manufacturer could beat China’s low prices. But this is changing partly because of import taxes that the Trump administration requires on purchases of many Chinese-made products. Excel plans to release its first completely American-made dryer in a few months. William Gagnon and his family own the company. He spoke with the Reuters news agency about the business and negotiating with suppliers of parts.
