FIELD: fire safety.
SUBSTANCE: fan comprises device for direction of air current, which is generated by airscrew of fan. This device for guiding is arranged in the form of cylindrical tubular shell, which is installed coaxially to axis of airscrew rotation, in which deflector system is located with blades for balancing and concentration of air current, which is generated by fan airscrew. At the outlet of specified deflector system with blades there is the second deflector system installed with concentric pipes, which are arranged in cylindrical tubular shell coaxially to axis of airscrew rotation.
EFFECT: developed fan for extinguishing of fires, due to availability of balanced and concentrated air current, provides for increase of distance between fan and object of fire extinguishing with preservation of equivalent or increased amount of removed smoke.
