ABSTRACT:
Systems and methods for high volume, low pressure foam generation are provided that have a wide range of applications, particularly in fire fighting and fire prevention fields. The foam may be effectively delivered to targets that have heretofore been difficult, if not impossible, to reach in a timely, cost effective and/or efficacious manner. Nozzles and nozzle-containing systems are provided for combining water, injected foam and air to generate and/or deliver high volume, low pressure foam. The foam generation systems may be part of portable units that may be worn or otherwise supported by a user (e.g., a back pack), manually transported (e.g., a push cart), or transported with power-assistance (e.g., a power-assist cart). The systems may also be vehicle-mounted. Exemplary nozzle systems include a diffuser unit that facilitates aeration of the water and foam mixture that is fed to the nozzle system. Further nozzle systems include a plurality of circumferentially arrayed nozzle jets directed toward a central axis of the housing for combination with an air flow that is fed thereto.
