Hydraulic systems experience dynamic, challenging operating environments in the real world, including ever-changing surge-and-flow conditions. To simulate actual operating conditions, the new ISO 23369 standard was developed that recognizes the importance of measuring performance as cycles and flow changes, instead of steady-state multi-pass flow (ISO 16889). This is one of the most significant recent developments in hydraulic filtration test standards, and it’s causing dramatic changes to filter technology, spurring the creation of media that performs better in contaminant retention under these ever-changing pressure and flow conditions.
With the 2021 industry ratification of ISO 23369, lab testing for hydraulic filtration more closely replicates the varying, or “cyclic” flow rates of real-world filter working conditions. This evolution of hydraulic filtration test standards has opened the door for new technology solutions.
The fine-fiber layer of Alpha-Web media enables high filtration efficiency during cyclic flow conditions, while minimizing dynamic events where particles are dislodged as the fluid flow changes. Alpha-Web is designed for enhanced filtration efficiency that is effective in real-world operating conditions.
To better protect your hydraulic equipment, you need filtration that’s been developed and tested to handle challenging operating conditions effectively and efficiently. Donaldson Alpha-Web hydraulic filtration technology offers that protection.
