AEROSHELL FLUID 41
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
de-activators and fOAm inhibitors are included in
this high viscosity index
fluid to enhance performance in hydraulic
applications. AeroShell Fluid 41 is
capable of wide temperature range
operation.
AeroShell Fluid 41 is dyed
red.
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°C to 90°C and
pressurised
between –54°C to 135°C.
AeroShell Fluid 41 should be used in
systems with synthetic rubber
components and must not be used in systems
incorporating natural rubber.
Refer to the General Notes at the front of this
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 use AeroShell
Fluid 41. The residual solvent contaminates the
hydraulic fluid and may lead
to corrosion.

*Superclean grades
The British
specification DEF STAN 91-48 covers two grades (normal and
superclean) of
mineral hydraulic fluid which differ only in their cleanliness
limits.
AeroShell Fluid 41 is manufactured to meet the superclean
requirements and
thus it also meets the requirements of the normal grade.
