Fomtec Enviro 3×3 Plus supplied by Dafo Fomtec
Fomtec Enviro 3×3 Plus is a novel multi-purpose alcohol resistant firefighting foam concentrate totally free from fluorinated surfactants and polymers (PFAS). Enviro 3×3 Plus is a member of the Enviro high performing fluorine free AR-capable product family.
- Fluorine free alcohol resistant foam concentrate
- Excellent fire performance on Heptane, Acetone and IPA with both potable and sea water
- Third party fire tested according to EN 1568-1, -3 and -4
The unique formulation of Fomtec Enviro 3×3 Plus enables the foam to rapidly cover burning surfaces and control of the fire. As a result, it is effective against hydrocarbon fires and with the presence of special polymers it is also very effective against polar solvents. In particular the performance on IPA is a significant improvement in comparison with many FFF type products.
The fire suppression mechanism of Fomtec Enviro 3×3 Plus 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. When applied on polar solvents a polymeric mem-brane is formed and makes it possible for the foam blanket to extinguish effectively. It also works on severe foam destroying liquids such as MTBE.
Fomtec Enviro 3×3 Plus should be used at a 3% proportioning ratio (3 parts concentrate and 97 parts water) for hydrocarbon fuels as well as polar solvents.
For use on Class A type fires, induction ratio of 0,3% to 1% is recommended depending on application and discharge device. When used with sea water an increased application rate or application duration must be adopted to maintain fire perfor-mance on hydrocarbon fuels.
Fomtec Enviro 3×3 Plus is intended for use on class B hydro-carbon fuels as well as polar solvents like isopropyl alcohol, methanol, ethanol, acetone etc.
Fomtec Enviro 3×3 Plus can be used as low and medium expansion foam. Especially suited for use in mobile firefighting by use of aspirating foam discharge devices such as foam branchpipes and monitors, where appli-cation rates and technique can be adjusted to the specificsof each incident. Or in systems designed for use with the product based on recommended minimum applications rates, application duration and discharge devices.
Fomtec Enviro 3×3 Plus is also effective against class A fires such as wood, paper, textiles etc. at 0,3% to 1% proportioning.

Fire performance & Foaming
The fire performance of this product has been tested and documented according to the “International Approvals” stated in this document. The use of the product should follow design guidelines appropriate to the type of system and application. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average expansion 7,5:1, average 25% drainage time 15:00 minutes using UNI 86 test nozzle according to EN 1568-3.
Fomtec Enviro 3×3 Plus can be proportioned at the correct ratio using proportioning equipment designed for the foam type. Fomtec Enviro 3×3 Plus is suitable for use with Type II (gentle application) and Type III (direct application) discharge devices. It can be used in low and medium expansion applications with all conventional aspirating discharge devices giving an expansion ratio of more than 7:1 for best performance. Fomtec Enviro 3×3 Plus is also suitable for use in CAF-systems.
Fomtec Enviro 3×3 Plus can be used together with foam compatible powders and other expanded foams.
It is suitable for all water types.
For mixing with other foam concentrates, contact Fomtec for advise and guidance. For material compatibility please refer to our Fomtec Technical Advices FTA 20 addressing the topic.
Fomtec Enviro 3×3 Plus is non-hazardous, biodegradable substance formulated using raw materials specially selected for their fire performance and their environmental profile. All raw materials are registered in European REACH-database. The product is totally free from fluorinated surfactants and polymers and other organohalogens, and therefore it does not contain any PFAS.
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.
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 foam concentrates, 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.
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 and IMO MSC.1Circ. 1312. 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.
