Particulates in hydraulic fluids can cause system failures through valve sticking, wear and blockages in nozzles and tubes. Particulates are especially challenging for modern hydraulic systems that operate at high pressures and have components with tight tolerances.
AeroShell Fluids 31 and 41 are formulated to protect hydraulic systems against failure by meeting super-clean standards. Their particulate contents are tightly controlled through special manufacturing processes, including multistage filtration, container cleaning just before filling and clean-room packaging conditions.
