LS aMax

Fomtec LS aMax is an alcohol resistant aqueous film forming foam concentrate (AFFF) multipurpose and high expansion foam concentrate consisting of a blend of fluorocarbon-, hydrocarbon surfactants and polymers, solvents and stabilisers. The fire suppression mechanism of Fomtec LS aMax on liquid surface fuels is utilising the foam blankets ability to block oxygen supply to the fuel and the high water content cools the fuel surface reducing the evaporation of flammable vapours. Additionally, the foam blanket prevents reignition of an extinguished fuel surface.

Application

Fomtec LS aMax is intended for use on class B hydrocarbon fuels such as oil, diesel, gasoline and aviation fuels as well as polar solvent fires such as IPA and acetone. Fomtec LS aMax can be used with all kinds on low, medium and high expansion devices. It is intended to be used at 3% proportioning. Fomtec LS aMax is also effective against class A fires such as wood, paper, textiles etc. at 0.3 to 1% proportioning.

Typical applications include high risk installations such as:

  • high expansion foam systems in warehouses, process areas, aircraft hangars etc.
  • Petrochemical and chemical industry
  • Airports and ARFF-vehichles

Suitable for mobile firefighting by use of aspirating foam discharge devices such as foam branchpipes and monitors, where application rates and technique can be adjusted to the specifics of each incident. Or in systems designed for use with the product based on recommended minimum applications rates, application duration and discharge devices.

Equipment

Fomtec LS aMax can easily be proportioned at the correct dilution using conventional proportioning equipment. The equipment should be designed to the foam type. Fomtec LS aMax can be used with low, medium and high expansion foam generators.
Used in Fomtec high expansion generators the below average values can be expected:
