Chicago, IL – June 13, 2025 – Sun Acquisitions, a prominent mergers and acquisitions firm, is pleased to announce the successful sale of Demco Products and 3B Filters Inc., a leading manufacturer and distributor of high-pressure filters. The business was acquired by strategic buyer Navistar Global.
The story of Demco Products and 3B Filters Inc. began in the early 1930s on Chicago’s South Side. Robert Dempster Sr. started his manufacturing journey in his basement, acquiring his first lathe to produce swivel joints for a lamp company. By 1950, Demco Products Inc. was officially established as a production and precision CNC machine shop. The company expanded its capabilities in 2001 with the incorporation of 3B Filters, which manufactures high-pressure filters sold globally to a diverse range of industries, including aerospace, petroleum, chemical processing, transportation, and defense.
“Selling a manufacturing business can be a daunting task, but Mike Walton made the entire process seamless and incredibly successful. From our first conversation, he was exceptionally communicative, always available to answer our questions and provide updates. His timeliness in every aspect, from preparing documents to coordinating with potential buyers, was truly impressive. Thanks to his hard work and strategic approach, we ended up with an incredible 12 offers, and we’re delighted with the final sale price,” said Michelle Dempster.
Mike Walton, Senior Advisor of Sun Acquisitions, was the lead advisor and managed all aspects of this client. After the sale of the business, Mike noted, “It was a pleasure working with the Demco Products and 3B Filters team throughout this process. Their dedication to quality and innovation has built a remarkable company, and I’m thrilled to have facilitated a successful transition for them.”
