Atmus Filtration Technologies Inc. designs and manufactures filtration products for commercial vehicles and off-highway equipment, with its business built around the Fleetguard brand. The company serves on-highway trucks and buses as well as agriculture, construction, mining, and power generation markets, supplying products that help lower emissions and protect engines and equipment. Its revenue mix is weighted toward the aftermarket, which creates a recurring replacement-part business alongside a smaller first-fit OEM component business. Atmus was separated from Cummins and began trading as an independent public company in 2023, carrying forward a long operating history in filtration and media technologies.
