FAYREKS frother
TU 2481 - 203 - 05744685 - 2003 is certified
Appointment
Biologically the FAYREKS soft frother - smachivatel (the WA type, S) is intended for prevention and fight against wildfires in land conditions and with application specialized aeromechanics, and also for suppression of the fires of classes A and B with use of foam of low and average frequency rate when using drinking, hard and sea water.
Structure
Water solution of mix of surface - active substances with the stabilizing additives.
Appearance
Transparent liquid without deposit.
Toxicity
Low - dangerous substance.
Warranty period of storage
In a polymeric container of the manufacturer - 60 months, in metal barrels - 12 months.
Packing
Polyethylene 20 l of the canister, steel 200 dm3 of a barrel, car - and railway tanks.
Application conditions
FAYREKS frother is applied to suppression of wildfires in the form of water solution with concentration of 0,5 - 1,0% (volume). FAYREKS frother is applied to suppression of the fires of classes A and B in the form of water solution with a volume fraction of 6% . Standard intensity of supply of working solution at suppression of hydrocarbonic fuels foam of average frequency rate - no more than 0,08 dm3/m2s.
