This item comes in 5 gal., 55 gal., and 265 gal. sizes.
ANSUL NFF-331 3%x3% Non-Fluorinated Foam Concentrate is a 3x3 alcohol-resistant non-fluorinated foam concentrate that provides superior fire and vapor suppression performance for Class B polar solvent, and hydrocarbon fuel fires.
This concentrate proportions in a wide range of equipment including in-line eductors and balanced pressure systems using bladder tanks or foam pumps and is suitable for sprinkler systems and various applications using standard discharge devices.
ANSUL NFF-331 foam is intended for forceful or gentle firefighting applications at 3% solution on hydrocarbon fuels and at 3% solution on polar solvent fuels in fresh, salt, hard, and brackish water. ANSUL NFF-331 foam concentrate utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance:
- The foam blanket has extended drain times to help block oxygen to the fuel and suppress fuel vapor
- On polar solvent fires, liquid drains from the foam blanket and forms a polymeric membrane which suppresses vapors and seals the fuel surface
- The water content of the foam solution produces a cooling effect for additional fire suppression
