Aeroshell - Fluid 41 Mineral Hydraulic Oil
Aeroshell - Fluid 41 Mineral Hydraulic Oil 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 whichprovide excellent low temperature fluidity as well as exceptional anti-wear, oxidation -corrosion inhibition and shear stability. In addition metal de-activators and foam inhibitorsare included in this high viscosity index fluid to enhance performance in hydraulicapplications. AeroShell Fluid 41 is capable of wide temperature range operation. AeroShell Fluid 41 is dyed red. The useful operating temperature range unpressurised is G54-C to 90-C.The useful operating temperature range pressurised is G54-C to 135-C. APPLICATIONS:AeroShell Fluid 41 is intended as a hydraulic fluid in all modern aircraft applicationsrequiring a mineral hydraulic fluid. AeroShell Fluid 41 is particularly recommended whereuse of a "superclean" fluid can contribute to improvements in component reliability, andcan be used in aircraft systems operating unpressurised between G54-C to 90-C andpressurised between G54-C to 135-C. AeroShell Fluid 41 should be used in systems with synthetic rubber components and must notbe used in systems incorporating natural rubber. Refer to the General Notes at the front ofthis section for further information. AeroShell Fluid 41 is compatible with AeroShell Fluids 4, 31, 51, 61 and 71 and SSF/LGF.Chlorinated solvents should not be used for cleaning hydraulic components which useAeroShell Fluid 41. The residual solvent contaminates the hydraulic fluid and may lead tocorrosion. SPECIFICATIONS: U.S. Approved MIL-PRF-5606H British Approved DEF STAN 91-48 Grade Superclean * (European production only) Meets DEF STAN 91-48 Grade Normal (European production only) Equivalent to DEF STAN 91-48 Grades Superclean * & Normal (U.S. production only) French Approved DCSEA 415/A Russian Analogue to AMG-10 NATO Code H-515* (equivalent H-520) Joint Service Designation OM15* (equivalent OM-18) *Superclean gradesThe British specification DEF STAN 91-48 covers two grades (normal and superclean) ofmineral hydraulic fluid which differ only in their cleanliness limits. AeroShell Fluid 41 ismanufactured to meet the superclean requirements and thus it also meets the requirements ofthe normal grade.
