Abstract
The fire suppressant foam generation and application apparatus produces a low moisture content fire suppressant foam for use in fire fighting applications. The reduction in the water content of the fire suppressant foam is accomplished by the use of pressurized gas in place of water along with a stata tube apparatus to agitate the foam/water mixture to create the fire suppressant foam. A pressurized gas operated pump can be used to actively draw the water/foam mixture from a supply tank and supply it under pressure to the stata tube and outlet line. This apparatus can be implemented as a backpack unit consisting of a storage tank, formed as a substantially U-shaped molded element, which contains the liquid foam concentrate/water mixture. A high pressure tank containing pressurized gas, either nitrogen or a nitrogen-air mixture, or other suitable gas mixture, is included in an aperture formed in the storage tank housing.
