Filters have always played an important role in maintaining the cleanliness of hydraulic fluids. They trap contaminants that may be in these fluids, preventing potential damage to sensitive components such as pumps and valves.
But like many components in modern hydraulic systems, filters are being tasked with doing so much more.
As Cory Gray, Global Sales Director for Eaton Filtration, explains in the Q&A at the top of today’s newsletter, hydraulic filters are no longer just a static component. Instead, they are becoming a part of the overall machine health-management system.
“The filter’s job will always be defined as ‘keeping particles out,’ but now customers are asking for more in terms of better visibility into oil condition, more predictable service intervals and filtration architectures that do not force equipment offline for routine maintenance,” he said.
This is leading to use of integrated sensors that can detect when a filter is clogged as well as different types of filter designs such as Duplex and changeover filter designs.
