Complete documentation
Manufacturer's description
AeroShell Fluid 41 is a mineral hydraulic oil manufactured to a very high level of cleanliness and possesses improved fluid properties. AeroShell Fluid 41 contains additives which provide excellent low temperature fluidity as well as exceptional anti-wear, oxidation - corrosion inhibition and shear stability. In addition, metal deactivators and foam inhibitors are included in this high viscosity index fluid to enhance performance in hydraulic
Applications
- AeroShell Fluid 41 is intended as a hydraulic fluid in all modern aircraft applications requiring a mineral hydraulic fluid. AeroShell Fluid 41 is particularly recommended where use of a "superclean" fluid can contribute to improvements in component reliability, and can be used in aircraft systems operating unpressurised between –54 0 C to 90 0 C and pressurised between –54 0 C to 135 0 C.
- AeroShell Fluid 41 should be used in systems with synthetic rubber components and must not be used in systems incorporating natural rubber.
- AeroShell Fluid 41 is compatible with the other AeroShell hydraulic fluids.
- Chlorinated solvents should not be used for cleaning hydraulic components which use AeroShell Fluid 41. The residual solvent contaminates the hydraulic fluid and may lead to corrosion.
- Due to its properties, it is also used in several industrial applications.
