AFFF 3% Ultra LT foam concentrate

Fomtec AFFF 3% Ultra LT 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% Ultra LT 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
  • Environmentally documented according to HOCNF
  • Approved to EN 1568, UL 162, ULC, ICAO, MED, GOST and RMRS
  • Freeze protected
  • Suitable for Class A and B fires
  • Low and medium expansion foam
AFFF 3% Ultra LT


Fomtec AFFF 3% Ultra LT should be used at 3% proportioning (3 part concentrate and 97 parts of water). May be used with all water types. Fomtec AFFF 3% Ultra LT 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% Ultra LT is suited whenever a low freezing point and high fire rating is required. Fomtec AFFF 3% Ultra LT is tested according to EN 1568, UL 162 7th Edition and ULC for use on class B hydrocarbon fuel fires such as oil, diesel, gasoline and aviation fuels. Fomtec AFFF 3% Ultra LT is effective against class A fires such as wood, paper, textiles etc. Tested and approved according to International Civil Organisation (ICAO) level B and level C for use in aircraft rescue and firefighting (ARFF) applications. Fomtec 3% Ultra LT is also approved for marine applications according to IMO Circ. 1312, MED Wheelmark and Russian Maritime Register of Shipping.

Typical applications include high risk installations such as:

  • Petrochemical and chemical industry
  • Tank farms
  • Warehouses
  • Marine vessels and offshore platforms
  • Civil defence
  • Industrial foam systems
  • Airports and ARFF-vehicles

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.

Fomtec AFFF 3% Ultra LT can easily be proportioned at the correct ratio using conventional proportioning equipment. The equipment should be designed to the foam type. Fomtec AFFF 3% Ultra LT is suitable for use in Type II (gentle application) and Type III (direct application) discharge devices as well as sprinklers according to EN 13565-2. It can be used in low and medium expansion applications with all conventional aspirating and non-aspirating discharge devices. Fomtec AFFF 3% Ultra LT is also suitable for use in CAF-systems.


Fomtec AFFF 3% Ultra LT can be used together with foam compatible powders and other expanded foams. It is suited for all water types. For mixing with other concentrates, contact Fomtec for advise and guidance. For material compatibility please refer to our Fomtec Technical Advices FTA 20 addressing the topic.


Fomtec AFFF 3% Ultra LT is formulated using raw materials specially selected for their fire performance and their environmental profile. All raw materials are registered in European REACH-database. Fomtec AFFF 3% Ultra LT is also registered in the NEMS database and each individual component is fully tested and documented to HOCNF regulations required for the NEMS registration. Fomtec only use C6 Pure fluorosurfactants in our AFFF formulations. Our film forming (AFFF) products contains no PFOS or PFOA in accordance with US EPA Stewardship Programme 2010/15 and EU Directive 2017/1000. More details can be found in the Material Safety Datasheet (MSDS). The disposal of spills of concentrate or premix foam solution should be made in accordance with local regulations. For more detailed information please consult our Fomtec Technical Advices FTA 40.


Storage / Shelf life

Stored in original unbroken packaging the product will have a long shelf life. Shelf life in excess of 10 years will be found in temperate climates. As with all foams, shelf life will be dependent on storage temperatures and conditions. For storage recommendations and material compatibility please refer to our Fomtec Technical Advices FTA 10 addressing the topic.

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, EN 1568, IMO Circ. 1312 or ICAO. 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.
