Anvol SWX FM

Anvol SWX FM
Castrol Anvol SWX FM are polyol ester fire resistant hydraulic fluids that meet HFDU 7th Luxembourg classification and specification tested to Factory Mutual Standard 6930 Group 1 classification. Castrol Anvol SWX FM products are outstanding in their category in providing a safe working environment and improved system reliability. Formulated to work in high–pressure hydraulic systems up to 7500psi.

Castrol Anvol SWX FM provides gear pumps with protection against wear equivalent to that of mineral oils. Castrol Anvol SWX FM is designed to combine fire resistance with superior system reliability and a reduced tendency to form varnish or deposit in valves, pipes and reservoirs. It also provides greater resistance to water by offering high levels of corrosion protection and ease of separation. Even in the harshest steel mill environment, Castrol Anvol SWX FM provides safety, protection and reliability. This has the added value of reducing failures and minimizing unscheduled downtime.
Castrol Anvol SWX FM is used in areas of the manufacturing industry were there is high risk of fire such as hot strip mills, coil handling facilities, pipe mills and continuous casters. The risk is minimized by Castrol Anvol SWX FM's high fire point and a low heat of combustion. It also offers the following product benefits:

  • Greater fire protection: With a high fire point and shear stability, Castrol Anvol SWX FM provides excellent fire suppression characteristics thereby creating a safer working environment and greater equipment protection.


  • System protection from water: Castrol Anvol SWX FM is designed to separate water to allow it to be removed from the system. Advanced corrosion inhibition protects ferrous components from any residual water. This reduces rust and leads to extended equipment life and a reduction in downtime.


  • Stability in harsh operating environments: Resistance to oxidation and thermal degradation and improved filter tolerance does the following:


    • Reduces deposits/varnish formation and the potential for valve sticking/failure
    • Ensures that product life is extended with greater drain intervals
    • Maintains fire protection characteristics with use

  • Superior equipment performance: Extended pump life and reduction in replacement/maintenance cost as well as longer life.

Compatibility with Seal Materials

Castrol Anvol SWX FM fluids are compatible with Acrylonitrilebutadiene rubbers (NBR), hydrogenated NBR and fluorocarbon rubbers (FKM). The Seal Compatibility Index (IP278) for Castrol Anvol SWX FM is comparable to mineral oils.
