ANSUL® NFF-3H 3% Non-Fluorinated Foam Concentrate (SFFF), 55 gallon (208 liter) drum

ANSUL® NFF-3H 3% Non-Fluorinated Foam Concentrate (SFFF) provides superior fire and vapor suppression performance for Class B hydrocarbon fuel fires that have low water solubility, such as various crude oils, gasolines, diesel fuels, and aviation fuels. It is not suitable for use on fuels with appreciable water solubility (polar solvents). The product is intended for forceful and gentle firefighting applications at 3% solution on hydrocarbon fuel fires in fresh, brackish, and salt water. It has been specifically designed for Type II, Type III, and sprinkler systems and is approved for use in airport firefighting applications by the International Civil Aviation Organization (ICAO level B).

The concentrate also has excellent wetting properties that can effectively combat Class A fires and is compatible with dry chemical agents. 

ANSUL® NFF-331 foam concentrate does not have any intentionally added PFAS (perfluoroalkyl substances) and is produced in equipment that has not handled PFAS chemistry. This concentrate thus complies with directives (EU) 2017/1000 on PFOA (perfluorooctanoic acid) and 2019/1021 (EU POPs directive), EU2024/2462 on PFHxA, and the latest (EU) 2025/1988 Directive on PFAS. ANSUL® NFF-331 foam concentrate has been subjected to OECD 301F testing and after 28 days is considered inherently biodegradable.

This concentrate is ideal for fixed and semi-fixed foam systems that use sprinklers, nozzles, foam chambers, and other standard discharge devices for various applications such as:

• Industrial chemical and petroleum processing facilities
• Fuel or chemical (non-polar) storage tanks
• Truck or rail loading and unloading facilities
• Flammable liquid (non-polar) containment areas
• Aircraft hangars
• Flammable liquid (non-polar) warehouse storage facilities
