FIRO A

Sigma Firo A range of hydraulic fluids are self-extinguishing anhydrous oils formulated from organic esters or synthetic oils and ultra-efficient additives. Hydraulic oils in the Sigma Firo A range have excellent fire-resistant properties allowing for complete safety of installations, operators and the environment. Further, they are biodegradable (according to standard OECD 301B).
