Overview
Donaldson Was the First To Introduce Fully Synthetic Media, but We Didn’t Stop at One Good Idea – Our Innovation Continues Today
Donaldson knows transmissions, and we know the best filter media to keep transmission fluid clean. Why? Because we’re industry leaders in filter media technology development and our scientists and engineers are constantly researching new and improved formulations to meet our customers’ specific needs.
Filtration Development, Testing and Analysis
Developing media technology that provides exceptional transmission fluid cleanliness and meets expected service life intervals is nothing new for our engineers. Donaldson was the first company to bring fully synthetic media to the market in the 1980s, and this media is now the standard for extended life and/or enhanced transmission and gearbox system protection needs.
We provide a variety of filter medias that have been tested and proven over time to meet the most stringent transmission system design requirements. In addition to improvements to current technology, our research team is also developing brand-new technologies that will attain even higher levels of performance to become our future “standards.”
In multiple research facilities around the world, our in-house scientists and engineers continually develop and refine a range of media options to meet the present and future requirements of our customers and the heavy-duty equipment industry.
Features
Fine or Large Contaminants, Dynamic or Steady-State Flow, We Have the Filtration Media To Suit Your Transmission Conditions
Donaldson offers several options so OEMs can choose the best filtration media to keep their transmissions and gearboxes running smoothly. From synthetic to wire mesh media, we have the right media for your application.
Synteq XP™ Synthetic Media
We specifically developed our groundbreaking Synteq XP media to address the numerous challenges of today’s transmission and gearbox systems. This high-performance filter media takes filtration to a higher level by providing enhanced system component protection options. These options include optimal protection via higher efficiency contaminant retention or filter life that extends up to two to three times that of traditional media. Synteq XP media offers a consistently lower pressure drop than most competitors, which reduces the reliance on bypass as it allows more oil flow during a cold start. It also results in greater system efficiency, less energy loss, and extended filter life. For best-in-class contaminant retention, Donaldson filters can be used with Synteq XP fine fiber media.
Synteq™ Synthetic Media
For media with predictable filtration efficiencies that remove specific contaminants and take dirt-holding capacity to the max, try Synteq synthetic media. The manmade fibers in Synteq are smooth and rounded and provide low-flow resistance. The low-inhibition fluid flow is due to the consistent shape of the fibers that allow for control of the fiber size and distribution pattern throughout the media mat. The consistency of the fiber shape maximizes contaminant capture surface area as well as specific pore size control.
Cellulose Media
Cellulose fibers are microscopic, irregularly shaped, and sized wood fibers that are held together by resin. Smaller pores in cellulose media means it often has lower beta ratings. The smaller media pores result in a higher pressure drop due to increased flow resistance. For a variety of petroleum-based fluids, cellulose provides effective filtration; however, in certain applications, it results in lower filtration performance compared to synthetic media.
Wire-Mesh Media
Wire mesh media is available in multiple grades and consists of stainless steel, epoxy-coated wire mesh. It is typically applied to capture very large, harsh particulates that would tear normal filter media. Wire mesh media can also be useful as a coarse filter in viscous fluid applications.
