FOMTEC AFFF 3% A foam concentrate

Fomtec AFFF 3% A is an aqueous film forming foam concentrate (AFFF) consisting of a blend of fluorocarbon-, hydrocarbon surfactants and various solvents and stabilisers. Only C6 Pure fluorosurfactants are used in Fomtec AFFF-formulations. Fomtec AFFF 3% A utilises the unique film forming effect to cut off oxygen supply to the fire and the oleophobic properties of the foam enables a stable foam blanket to suppress reignition of the fire.


  • Short chain C6 Pure fluorochemistry
  • Approved to EN 1568
  • Suitable for Class A and B fires
  • Low and medium expansion foam
  • Freeze protected versions available

Fomtec AFFF 3% A should be used at 3% proportioning (3 part concentrate and 97 parts of water). May be used with all water types. Fomtec AFFF 3% A can be stored as premix when blended with fresh water. For use on Class A type fires, induction ratio of 0,3% to 1% is recommended depending on application and discharge device.


Fomtec AFFF 3% A is intended for use on class B hydrocarbon fuels such as oil, diesel, gasoline and aviation fuels. Fomtec AFFF 3% A can be used with all kinds of low and medium expansion devices. Fomtec AFFF 3% A is also effective against class A fires such as wood, paper, textiles etc.
Typical applications are general firefighting of flammable liquids. Typical users are fire departments and general industry. Suitable for mobile firefighting by use of aspirating foam dis-charge devices such as foam branchpipes and monitors, where application rates and technique can be adjusted to the specifics of each incident. If the product is used in a fixed system the design should be based on recommended minimum application rates, application duration and type of discharge devices.

Inspection / Testing / Maintenance

All foam concentrates should be tested annually. Testing should be carried out by an approved laboratory certified to assess firefighting foam quality according to relevant standards, such as NFPA 11, EN 13565-2 or EN 1568.
Storage containers should be inspected and reevaluated for the suitability of the storage location regarding temperature fluctuations (temperature should be as stable as possible). Exposure to direct sunlight should be avoided.
