Enviro AIR


Fomtec Enviro AIR is a novel fluorine free firefighting foam totally free from fluorinated surfactants and polymers. Fomtec Enviro AIR is especially designed to be an effective fluorine free alternative for Aircraft Rescue and Fire Fighting (ARFF), fighting class B fires in aviation Kerosine jet fuel such as Jet A 1. Fomtec Enviro AIR should be used at 3% with fresh water for low expansion equipment such as monitors and handlines.


Fomtec Enviro AIR is intended for use on class B hydrocarbon fuels and is especially effective against fires in Kerosene fuels. Fomtec Enviro AIR is especially suited whenever a fluorine-free alternative with low viscosity is desired.
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. It is compatible with all dry chemical powders and can be used in powder/foam twin agent systems.

Fire performance & Foaming

The fire performance of this product has been measured and documented according to “International Approvals” stated in this document. The design parameters depend on type of system and application. The use of the product should follow design guidelines. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average expansion 8:1, average ¼ drainage time 6:00 minutes using UNI 86 test nozzle.


Fomtec Enviro AIR can easily be proportioned at the correct dilution using conventional proportioning equipment.
The equipment should be designed to the foam type.


Fomtec Enviro AIR can be used together with foam compatible powders and other expanded foams.
Fomtec Enviro AIR concentrate should not be mixed with other foam concentrates.
For material compatibility please refer to Fomtec Technical Advices FTA 20 addressing the topic.


Fomtec Enviro AIR is formulated using raw materials specially selected for their fire performance and their environmental profile. The product contains no intentionally added fluorinated surfactants and polymers and other organohalogens. Fomtec Enviro AIR is biodegradable and contains no PFOS or PFOA. The handling of spills of concentrate or foam solutions should however be undertaken according to local regulations. Normally sewage systems can dispose foam solution based on this type of foam concentrate, but local sewage operators should be consulted.
Full details will be found in the Material Safety Datasheet (MSDS). For more detailed information please consult 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.

Enviro AIR


The foam concentrate should be tested annually. The testing should be made by a suitable laboratory for analysis of foam concentrates and should measure: pH, specific gravity, expansion, drainage time. Storage containers should be inspected and reevaluated for the suitability of the storage location in regard to temperature fluctuations (temperature should be as stable as possible). Exposure to direct sunlight should be avoided.


We supply this product in 25 litre and 5 US gallon cans, 200 litre and 55 US gallon drums, 1000 litre and 265 US gallon IBC containers. Larger bulk supply is available on special request.
