The QUADRAFOG-RU (QUADRAFOG) manual fire nozzle with adjustable flow rate is designed to produce solid and sprayed jets.
With relatively small dimensions, it has a wide range of technical capabilities. It includes the capabilities of domestic hand-held barrels SRK-50, RSK-50, RSP-50, RSP-70 and RSKZ-70 at the same time, since the flow rates and technical characteristics of KVADRAFOGA actually not only combine the specified barrels in one, but also surpass them.
Provides effective protection for firefighters from thermal radiation by creating a 120° water protective screen.
It has a function of washing the barrel when it gets dirty, without disconnecting the hose line.
Additionally, it is equipped with quick-release universal foam nozzles for producing low- and medium-expansion fire-extinguishing foam.
Depending on the performance and working pressure, the barrel is produced in three modifications.
Main technical characteristics:
