Description

Castrol Anvol SWX 46 FM and SWX 68 FM are HFDU Polyol ester type hydraulic fluids as defined by ISO 6734/4 and ISO 12922 (1). They are fully approved by FM Global (Factory Mutual) as industrial Fire Resistant Hydraulic Fluids. The Anvol SWX FM range is outstanding in their category in providing a safe working environment, improved system reliability and biodegradability.

Application

Formulated to work in high-pressure hydraulic systems up to 7500 psi. Anvol SWX FM provides gear, vane and piston pumps with protection against wear equivalent to that of mineral oils.

Anvol SWX FM is classified as follows:

• ISO 6743/4 – Hydraulic Oils Type HFDU

Anvol SWX FM grades meet the requirements (for appropriate viscosity grade) of:

• Oilgear Towler
• Bosch Rexroth
• FM Global 6930 Approved (FM Standard 6930 Jan 2002 Category 1)
