Fomtec Enviro eMax is a new generation of high performance fluorine free alcohol resistant multipurpose foam concentrate that has no intentionally added fluorinated surfactants and polymers (PFAS). It consists of a blend hydrocarbon surfactants, blended with various solvents, and stabilizers. Fomtec Enviro eMax have been designed to be used as low, medium and high expansion. Fomtec Enviro eMax should be used at 2-3% proportioning in potable water.
Fomtec Enviro eMax is intended for use on class B hydrocarbon fuels such as oil, diesel, gasoline and aviation fuels, as well as polar fuels like acetone, isopropyl alcohol etc. Fomtec Enviro eMax can be used with all kinds on low, medium and high expansion devices.
Fomtec Enviro eMax is also effective against class A fires such as wood, paper, textiles etc at 0.5-1% proportioning.
Typical applications are high expansion foam systems in ware-houses, process areas, aircraft hangars or other applications where three-dimensional fire can occur.
Suitable for mobile firefighting by use of low expansion aspi-rating foam discharge devices such as foam branchpipes and monitors. Or in systems designed for use with the product based on recommended minimum applications rates, applica-tion duration and discharge devices.

The fire performance of this product has been measured and documented according to “International Approvals” stated in this document. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average low expansion 8:1, average ¼ drainage time 9:30 minutes using UNI 86 test nozzle.
Used in Fomtec high expansion generators the average values to the right can be expected:
| Generator | Expansion @ 4 bar |
| Fomtec Bele L | 380:1 |
| Fomtec Bele S 400 | 550:1 |
| Fomtec Bele S 800 | 500:1 |
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 depen-dent on storage temperatures and conditions. For storage recommendations and material compatibility please refer to our Fomtec Technical Advices FTA 10 addressing the topic.
The Fomtec Enviro range comprises an extensive range of non-PFAS based foams suitable for use Emergency Response missions and System applications. Enviro foam concentrates are available for class A, class B fire hazards and products are avail-able for low, medium, and high expansion discharge devices.
