Hydraulic filters Triboguard high-performance hydraulic filters use state-of-the-art hydraulic filtration technology to protect systems. Polymer pack design enables long life and is engineered to provide structural strength with minimal flow resistance while maintaining high removal efficiencies. Synteq filter media allows higher initial cleanliness and system protection. Design also allows for lower pressure drop in high viscosity situations.
