Castrol Aero HF 585B is a mineral oil based low viscosity hydraulic fluid which is intended for use in hydraulic systems
where rapid system response is required, particularly at low temperatures. Castrol Aero HF 585B is ideally suited to
accumulator driven emergency control systems.
Castrol Aero HF 585B is produced from low viscosity highly refined mineral basestock, shear stable viscosity index
improver, antioxidants, corrosion inhibitors and anti-wear additives.
Hydraulic systems operating at low ambient temperatures or driven by accumulators, such as Emergency Shut Down
Valves and Watertight Door Controls.
Conditions of Use
The wearing of impervious PVC (or other suitable material) apron and gloves, together with eye protection is
recommended. Contaminated clothing should be changed immediately and thoroughly cleansed before re-use. This
applies especially to under garments.
Castrol Aero HF 585B is available globally and combines excellent protection with performance and versatility in
Offshore operations to provide the following key benefits:-
Excellent low temperature fluidity.
Good viscosity characteristics over a wide temperature range.
Good elastomer compatability.
Good compatability with metals
