Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
A fire fighting supply system utilizing pneumatic atomization for extinguishing fires, comprising in combination: a vehicle having emergency warning devices and storage areas for fire fighting equipment; a water tank and pump assembly for supplying and pumping water to an aftercooler, and a hose and nozzle assembly; an air compressor for supplying a pressurized flow of air to the hose and nozzle assembly; said water operated aftercooler disposed to cool warm compressed air from said air compressor; manual and automatic ratio flow regulating devices; said hose and nozzle assembly comprising a live hose reel, a hose, and a nozzle apparatus with a plurality of pneumatic atomizing nozzles.
