Description Technical Specs Extended Information
Class B Foam Agents are ideal for suppressing fires involving petroleum-based products, LNG, rubber, and flammable and combustible liquids; such as diesel fuel, crude oil gasoline and ethanol. ANSULITE Alcohol-Resistant Aqueous Film-Forming Foam (AR-AFFF) Concentrates produce a foam that is effective on hydrocarbon fuels as well as fuels such as methanol, ethanol and acetone which have appreciable water solubility or miscibility. AR-AFFF exhibits the best cross-functional performance for flame knock-down, burnback resistance, extended vapor suppression, manufacturing and proportioning consistency, and the longest potential shelf life.
  • ANSULITE ARC 3% or 6% AR-AFFF Concentrate can be used on either conventional Class B fuels or the polar solvent type Class B fuels. Because of the low energy to make foam, it can be used with both aspirating and non-aspirating discharge devices
  • To provide even greater fire protection capability, it can be used with dry chemical extinguishing agents without regard to the order of application to provide even greater fire protection capability. However, with the velocity of the dry chemical discharge, care must be taken not to submerge the polymeric membrane below the fuel surface
  • ANSULITE ARC 3% or 6% AR-AFFF Concentrate is intended for use as a 3% or 6% proportioned solution (depending on the type of fuel) in fresh, salt or hard water. It may also be used and stored as a premixed solution in fresh or potable water for use with the ANSUL Model AR-33-D wheeled fire extinguisher
