ABSTRACT:
The invention provides an air delivery system for emergency workers, wherein the air delivery system is adapted to be used with a water hose. The system includes a source of compressed air fluidically connected to the water hose to purge water from the water hose. Pressure adjusting means adjust the compressed air pressure to less than approximately 300 psig. Means are provided for further reducing the air pressure, after the water is purged, to a pressure in the range of approximately 8-50 psig. The system further includes means for transferring air from the air hose to a breathing cavity of the worker.
