【AeroShell Fluid 31】
Synthetic hydrocarbon-based aircraft hydraulic oil
AeroShell Fluid 31 is a synthetic hydrocarbon-based aircraft hydraulic fluid that has significantly improved flame retardancy over conventional petroleum products.
.
AeroShell Fluid 31 uses specially designed base oils that have a relatively high flash point, excellent low temperature properties, and good oxidation and thermal stability. In addition, AeroShell Fluid 31 uses high-tech additives to provide protection against oxidation, corrosion, wear and foaming. AeroShell Fluid 31 is ultra-clean filtered to ensure optimal
performance required by particle monitoring systems.
Operating temperature range: –40°C to +205°C (–40°F to +401°F).
■Range of Application■
AeroShell Fluid 31 is suitable for use in autopilots, shock absorbers, brakes, flight control systems, hydraulic servo control systems and other systems using synthetic elastomer seals.
Today, more and more aircraft manufacturers are recommending the use of these hydraulic fluids in aircraft hydraulic systems to replace mineral hydraulic fluids, as they require hydraulic fluids with better flame retardant properties.
AeroShell Fluid 31 is a synthetic hydrocarbon oil and must not come into contact with incompatible sealing materials.
AeroShell Fluid 31 is compatible with AeroShell Fluids 41 and 61 and can be used in systems using MIL-PRF-5606, MIL-PRF-6083, MIL-PRF-87257 and MIL-PRF-46170 hydraulic fluids.
