Donaldson Co. Inc., a global leader in engine filtration, has announced it has acquired 100 percent of the shares of Engineered Products Co., a leading designer and manufacturer of indicators, gauges, switches and sensors for engine air filtration and liquid filtration systems.

Founded in 1977 and based in Waterloo, Iowa, Engineered Products generates annual sales of approximately $9 million through its well-known Filter Minder brand. Filter Minder products connect to air and fuel filtration systems to measure, indicate and predict remaining filter life.

“The acquisition of Engineered Products supports our strategy of technical leadership in filtration products for both our OEM Customers and their end users of our filters,” said Tom Scalf, Donaldson’s senior vice president for Engine Products. “We see an increasing need for measuring and monitoring filter life in diesel powered equipment, and communicating filter status information visually, electronically and remotely as vehicles become increasingly connected with fleet management systems. The information from Filter Minder products helps equipment operators maximize the performance and uptime of their equipment, and plan their filter changes.”
