ABSTRACT:
The drawings and description describe a hand-portable fire fighting, positive pressure blower with water misting provisions 10 for cooling and producing positive pressure within a smoke filled space and to remove the smoke, heat and carbon dioxide from the area to facilitate extinguishment of the fire and subsequent overhauling. The blower 10 includes a portable support frame 12. An internal combustion engine 13 is mounted thereon with a drive shaft mounted propeller 18 for generating an airstream to be directed into the smoke filled space. Misting nozzles are mountable to the frame and are positioned thereon to direct a spray mist into the airstream from positions radially outward of the airstream. The nozzles are positioned in relation to the direction of propeller rotation so the spray mist will be carried over a maximum distance. The water spray mist substantially cools the airstream which then absorbs much of the heat in the area. The mist also travels with the airstream to help extinguish the fire and to carry products of combustion away. The area is thus left cooler and with greater visibility to enable fire fighters to attack the fire.
