Donaldson Filters Donaldson Company, Inc. is a global leader in providing air, oil and fluid filtration solutions for engines and industries. For over 100 years, Donaldson has been solving customers' complex filtration needs. Currently, we are one of the largest suppliers of unique filtration technologies and high-quality filters and parts.

Oil filters More and more stringent environmental protection requirements force manufacturers of combustion engines to introduce new technologies that limit the emission of harmful substances into the atmosphere. This also applies to the cleanliness of the engine oil and minimizing its entry into the combustion chamber in the crank system.

Donaldson has been producing oil filters since 1980. Extensive experience in this field allows us to provide high-quality oil filters that meet the latest environmental requirements. The offer includes 3 types of oil filters: full flow, by-pass and two-stage (a combination of the previous two).

Donaldson air filters are a world leader in the design and supply of complete intake systems for combustion engines. Many years of experience in this field allow us to provide the right solution for every application, especially those operating in the harshest conditions.

We offer a wide range of air filter inserts used in most vehicles and machines. The proposed filters ensure the appropriate amount and quality of air supplied to the engine throughout the entire period of use. Thanks to this, it is less loaded and, as a result, its service life is extended.

Fuel filters Modern combustion engines, due to their technologically advanced design, require increasingly higher fuel quality. The current standard for purification accuracy is 7-25 µm for pre-filters and 3-5 µm for fine filters, and water removal is over 99%. Donaldson engineers strive to stay ahead of these requirements by constantly working on the development of new filter materials.

We offer can fuel filters and filter inserts for most heavy equipment, machines and vehicles. Donaldson products are ideal for difficult operating conditions thanks to their high quality and durability.
