Why Choose Donaldson

What really separates one filter manufacturer from another? Is it quality, performance,
service, value. warranty you can really trust? With Donaldson, you don’t have
to choose one over the other – because you get it all.

Filters & Parts

We deliver a full line of low, medium, high-pressure and off-line filtration systems – plus a
complete portfolio of aftermarket replacement filters.

Cleaning hydraulic fluids for more power

Hydraulic fluid is the medium by which power is transferred in hydraulic machinery. It provides the life blood for operation and the power to get the job done. It is essential, therefore, that hydraulic systems operate efficiently.

Contamination in hydraulic systems represents a major threat to efficiency and productivity. Indeed, more than 80% of all hydraulic failures can be attributed to contaminated fluids. This includes failures in hoses and fittings as well as pumps and valves.

There are three types of contamination, solid, liquid and gaseous contamination. Filters are used for effective particle separation to ensure the operating function of the components and therefore the entire system. They play an essential role in ensuring that the systems operate reliably and economically with high availability and low maintenance intervals.

Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery.
