F3 foam nozzle for fluorine-free fire-fighting foam
When it is not possible to secure an object from above by means of foaming/cooling, the F3 Nozzle can be a solution.

The F3 foam sprayer is a directional sprayer that can be used for both cooling and foaming a protected installation/object. Because the sprayer has a relatively large throw distance, it does not need to be positioned above the object to be protected. Furthermore, the sprayer has a well-developed spray pattern, allowing for efficient cooling.
