Castrol Aero HF 585 B is a red 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.
Aero HF 585 B meets the following specifications:-
DEF STAN 91-48 (normal production)
Joint Services Designation OM-18
US Military MIL-H-5606H.

For superclean requirements please refer to Brayco Micronic 756

When compared to conventional mineral based hydraulic oils Aero HF 585B offers the following advantages:-

• Excellent low temperature fluidity.
• Good viscosity characteristics over a wide temperature range.
• Good elastomer compatability.
• Good compatability with metals.
