The basic component of the gun  is the flow-through pipe of a special profile, provided – on one side – with a cap of 75 (for connection of a typical pressure hose), and – on the other side -  the pipe is terminated with a general-purpose head enabling adjustment of the water output and stream kind. There is a possibility of changing the extinguishing stream output ranges. The gun is provided with a pressure gauge indicating the water pressure value. The gun in the portable version is supported on a special-purpose frame enabling arbitrary displacement of the same. The rotary components enable turning through  360° in the horizontal plane and from  -15° up to +90° in the vertical plane.
