The Eurosafe CAFS system, developed from decades of firefighting experience, connects a water supply to open foam nozzles via a network of dry pipework. It uses pressurized nitrogen or air stored in high-pressure cylinders to propel water and foam from their respective vessels. Water and foam are mixed through a foam proportioner before being directed through CAF Generators, where nitrogen is added to create compressed air foam.

These systems are custom-built to meet specific project needs while adhering to a pre-engineered design manual. The number of nozzles required determines the necessary quantities of water, foam, and propellant gas. Careful design of the distribution piping is essential to ensure optimal performance and coverage.
