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.
Explore our solutions for hydraulic filtration applications
Heavy industries
The workpieces must run safely through the entire production process. Our DWF duplex filters can keep the oil clean and running 24/7.
Marine
Full speed ahead. Our change-over stainless steel duplex pressure filters (DU) continuously and reliably clean the lube oil in marine transmissions.
Wind power
The light and compact TWF Twinfil system combined with 01.NR DIN 24550-4 elements, provides reliable and efficient performance for gearbox lubrication systems in all weather conditions.
Mining
No stone is left unturned. Our hydraulic filters reliably remove contaminants from the lubricants in tunnel drilling machines, even under high pressure.
Automotive industry
Runs like a well-oiled machine. High-performance filter elements of our EasyFit range filter oils and cooling lubricants in OEM quality.
Refrigeration
Cool filters for cool applications. The combination of high-performance LF, DU and EDA pressure filters and special IS07 filter elements protects lubricant in refrigeration compressors and keeps cooling applications at the right temperature.
