Cummins Filtration: A Legacy of Heavy-Duty Filtration Excellence

Cummins Filtration — best known through its iconic Fleetguard brand — is one of the most trusted names in filtration technology for diesel and gas-powered equipment worldwide. Cummins Filtration traces its roots back to 1958, when the Cummins Engine Company launched a single filter production line in Seymour, Indiana, to supply high-performance filtration for its own diesel engines. What started with two employees sewing cloth-bag lube oil filters has grown into a global industry leader with an enormous catalog spanning thousands of part numbers.

Engine oil filters, fuel filters, air filters, hydraulic filters, and fuel water separator filters are all core pillars of the Cummins Filtration lineup. The brand markets these products to both original equipment manufacturers and the aftermarket replacement service channel, covering trucks, construction equipment, agricultural machinery, marine applications, power generation, and more.

Over the decades, Cummins Filtration pioneered a number of innovations that reshaped the heavy-duty filtration industry. Notable milestones include the introduction of combination full-flow/bypass filtration in the 1980s, multi-layered StrataPore filter media in 1986, centrifugal filtration in 2000, and fully non-metallic lube and fuel filters in 2005. This culture of engineering-led advancement has kept Fleetguard at the forefront of filtration science across multiple generations of equipment.

All Fleetguard products are engineered to meet or exceed OEM specifications, making them a reliable choice whether you are servicing a fleet of long-haul trucks, maintaining heavy construction equipment, or keeping a diesel pickup running at peak performance. The brand backs its products with one of the most comprehensive warranties in the filtration industry, underscoring its confidence in design and manufacturing quality.

In 2023, Cummins Filtration transitioned into an independent, publicly traded company rebranded as Atmus Filtration Technologies, while continuing to support and grow the Fleetguard product portfolio. This evolution reflects a long-term commitment to sustainable filtration innovation while preserving the engineering pedigree that professionals have relied on for more than six decades.
