HYDRA-GUARD BIO-SYN FR 68 HYDRAULIC OIL
HYDRA-GUARD BIO-SYN FR 68 is a biodegradable, synthetic, low flammable hydraulic fluid based on organic esters and proven additives. It has been specifically formulated for use in applications exposed to fire hazards.
These ISO Class HFDU fluids are specially designed to provide good performance in conventional hydraulic systems and have better fire resistance than mineral oils. HYDRA-GUARD BIO-SYN FR 68 Hydraulic Oil is also biodegradable with a low ecotoxicity, and is particularly suited for use in environmentally sensitive areas.
HYDRA-GUARD BIO-SYN FR 68 is classed as a Environmentally Acceptable Lubricant (EAL).
Excellent fire-resistance
Readily biodegradable – >60% after 28 days when tested in OECD 301 B (CO2 evolution test)
Excellent viscosity/temperature characteristics – minimum change of viscosity with variation in
operating temperature, giving true ‘multigrade’ characteristics
Pump anti-wear protection similar to mineral hydraulic oils
Low flammability maintained during the life of the fluid
Excellent stability against oxidation
Good deaerating and foam suppressing properties
Excellent corrosion protection
Good compatibility with seals and gaskets made from synthetic material
Compatible with mineral oil and most materials / seals specified for use with mineral oils (not natural rubber)
Classification HFDU according to ISO 6743-4
ISO 12922 Specifications for fire-resistant hydraulic fluids – category HFDU
The European Communities Mines Safety Commission 7th Report –
Requirements for less flammable fluids (‘7th Luxembourg Report’)
