ATMU

Atmus Filtration Technologies Inc.

A maker of filters for engines and vehicles, Atmus Filtration Technologies designs fuel, oil, air, and coolant filters sold under the familiar Fleetguard brand, used by truck fleets, farmers, and heavy-equipment owners around the world. The business began in 1958 as Seymour Filtration Co., a single production line set up in Indiana to support Cummins diesel engines, and grew inside Cummins for decades before becoming its own independent, publicly traded company in 2023. Its name comes from "atmosphere," a nod to keeping the air clean.
