Seventy-five percent of hydraulic system failures are due to contamination. In real-world conditions, filters are subjected to changing flow rates. Today’s lab testing of hydraulic filtration replicates the cyclic (varying) flow rates that occur in real-world filter working conditions, as a result of the 2021 ratification of ISO 23369, allowing for new technology solutions. Measuring performance as cycles and flow changes, rather than steady-state multi-pass flow (ISO 16889), is a significant development in hydraulic test standards.

Donaldson Filtration Solutions introduced Alpha-Web media, a fine-fiber layer that enables high filtration efficiency during cyclic flow conditions and minimizes events that dislodge particles as fluid flow changes. This makes Alpha-Web effective in real-world operations.

This improved contaminant retention through filtration helps ensure better and longer equipment performance with less wear and damage, and reduces unplanned downtime by keeping hydraulic oil cleaner.

Compared to synthetic media, testing has shown Alpha-Web improves hydraulic fluid cleanliness levels by two ISO codes, with up to four times cleaner hydraulic fluid and extended component life. Fluid cleanliness improved by two ISO codes can significantly extend component life (by as much as 60%) according to the industry-accepted authority, the Equipment Life Extension Table by Noria Corporation.
