Clean Diesel Carts are the perfect solution for fuel transfer and kidney loop applications. A high efficiency fuel filter and water absorber (included) work together to ensure that your diesel is both clean and dry.

Donaldson Clean Diesel Kits provide simple, effective outlet filtration on fuel dispensers to allow you to pump clean fuel into your vehicles and equipment.

Clean Solutions filter heads feature robust, aluminum construction with steel inserts to minimize metal-to-metal galling between the head and the filter, even when used with diesel fuel.

Premium Donaldson Blue® Clean Solutions filters provide unsurpassed cleanliness in a single pass. They are perfect for inlet and outlet filtration applications. Their spin-on design enables fast and simple filter changes without special tools and provides greater protection from contamination during service than traditional cartridge-style filters.

Clean Solutions Filter Manifolds extend service intervals or increase flow rate beyond the capability of a single or dual filter head. Two or more manifolds can be plumbed together to accommodate even larger flow rates.

Electrical or visual Filter Service Indicators tell you when to change your filters – helping you maintain desired ISO cleanliness levels. Visual and electrical indicators are all available to help you maintain and analyze system performance and optimize filter service cycles.

Fluid analysis provides a snapshot of what is happening inside your equipment. It tells you the condition of the fuel or lubricant and identifies component wear and contamination. The Donaldson Patch Test Kit allows you to conduct on-site particulate analysis in as little as ten minutes. It quickly and reliably assigns a three-digit cleanliness code per ISO 4406-1999 to a given fluid sample.
