High Expansion® F3 2% concentrate is designed for extinguishing fires where total flooding application is desired. High-expansion foam systems provide extinguishment in two ways: total flooding limits the oxygen required to support free combustion, and a slow continuous release of foam solution allows for maximum cooling and penetration.
